Hello Carl; You also asked about clutch removal, this should help.
R² Drive Link Outboard Clutch by Drivelink.blogspot.com

Check the IPL for your saw to see if any special tools are needed. Poulan (Craftsman, Jonsered, Husky) clutch removal tool part number 530031112 if needed, is under $5 from many sources (look at the visible area between the weights if 2 small round sockets are visible you need the tool).
There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of nylon rope (nothing left behind) be used instead of the piston stop (retain 6″ ± so you can remove it). Make certain the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
99.9% of clutches have left hand threads (tighten it to loosen it). If a finger nail held in the thread and rotated clockwise comes off the shaft it is a left hand thread. If it pinches against the clutch it is a right hand thread.

This length differs from the overall length, which manufacturers use less than the cutting length. A Poulan 14 chainsaw can operate with a bar that`s 12, 14, 16 and 18 inches length. However, a larger bar may not always give the best cutting performance.
For most projects, you`ll want a chainsaw that extends approximately 2-4 inches beyond what it is you`ll be cutting. For example, if you`re cutting a tree trunk that is approximately 12 inches wide, a 14″ or 16″ chainsaw would be ideal.
If you change the bar, you must also change the chain. The chain needs to fit precisely onto the bar in two ways. First, it must be exactly the right diameter to fit snugly around the bar and sprocket. Second, the drive links, on the inner ring of the chain, must fit exactly in between the guide slots on the new bar.
Typically a chainsaw with a shorter bar around 14” and smaller is enough for property maintenance, trimming, pruning, and cutting down broken tree limbs. On the other hand, cutting down small trees, thick branches, and cleaning up storm damage will need a longer bar around 16”-20” to make the job easier and safer.
For example, larger chainsaw bars work best with more powerful saws because it takes more energy to drive a chain around a long bar. That`s why electric saws use bars 18″ and shorter. Similarly, chainsaw chains are measured to fit certain bars.
1. Engine size is measured in cubic centimeters (cc) or cubic inches. In general, the bigger the number, the more powerful the engine. Most homeowners will do fine with a saw in the 32 cc to 45 cc range.
The chain gauge and bar gauge must match otherwise it will not fit properly. Usually, a larger pitch chain will have larger teeth that take bigger cuts out of the wood.

Recommended chainsaw bar length for home use

A 16 to 18-inch bar should be enough to get the job done. This longer bar length will also work for cutting down small trees or removing shrubs.

Many homeowners find that a 14- to 16-inch chainsaw is a good length for them. That`s long enough to limb-up trees, cut down small trees, and cut most firewood, but it`s also short enough that it`s easy to control the saw.
The most common chainsaw bar sizes are 12 to 20 inches, but they come in sizes as large as 72 inches, typically for professionals. The longer the bar, the heavier the chainsaw.
But, no. Chain bars are not universal because they have varying sizes and shapes that fit into the chainsaw. In this case, the chain gauge and pitch should be equivalent to the chain and engine size. For this reason, any bar will not correctly mount with other chainsaws.
In-Tree and Electric Saws

Stihl`s electric saws come in three different sizes: the MSE 140 can handle a bar between 12 and 16 inches, the MSE 180 can take a bigger 18-inch bar, and the MSE 220 takes a bar between 16 and 20 inches.

Husqvarna 141 piston ring, what is the required gap for the ring? Also, does it matter which way the piston is positioned in the cylinder, there is no arrow or difference that I can tell by looking at it.
ANSWER : It’s been a few years but I’ve installed piston rings in many small engines. Many rings are beveled or rounded on the top outside to prevent excessive cylinder wear or scaring the cylinder wall. The bevel should be very slight and very hard so see. Some may have a small dot or marking cast into the ring near the end/split. If that is the case the ring should be installed with the marking turned toward the cylinderhead. Hint, lube the piston, rings, and cylinderwall before installing the piston. Gene

55 rancher-put new after market piston,ring and cylinder new sparkplug,cleaned carb,tried adjusting hi lo-new gas filter,new fuel line ,cleaned air filter-will start but on acelleration bogs and dies took to chain saw teck and they tried everything even replaced the carb with one from a working saw they said maybe the after market part is different but i got a complete piston,ring and cylinder so why would that make a difference at wits end
ANSWER : I had a very similar problem with a stihl 029 farm boss.I did everything you did except I took it to a shop to do the piston and ring replacement. When I got it back the first time it would run for about two mins. then die.I fought it for a couple of weeks then took it back and expressed my displeasure. Then checked it all over and replaced piston and ring again and it runs great. They told me they could not get the right compression with the first one and thought the groove for the ring was cut to deep.I hope this is of some help to you. Thank you.

Honda GX390: Starts OK on idle, idles for 20 seconds or so and dies. Also dies if attempt to increase throttle. Gasoline is new. Cleaned carb and jets – no help. Installed NEW carb, new spacers, new gaskets: SAME PROBLEM, NO CHANGE! Yes, gas is in tank and it’s new. Yes, the gas lever is in the ON position. Yes, it idles with the choke in OFF position. NO it will not run more than a minute, less than that if you attempt to increase throttle. Gas lid vent WORKS; fuel line is clear of obstruction and works fine. ON/OFF switch is ON. Changed oil to proper level with new oil: 10W40; – not over-filled or under filled. It’s 8 years old but only used about 10 to 15 hours per year since new. Nothing I’ve done has changed a thing (except drain cash from my pocket). What does it take to make this machine work again?
ANSWER : Replace the magneto that incorporates the sparkplug wire. The windings to the magneto are weak causing it to die out

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

Remove air filter and carb to see scored cylinder wall(on hot side)

I got a husqavarna 36 chainsaw and i just recently rebuilt it ,putting a new piston and ring in it.the problem is i cant get it to start by pulling it. it wants to start but doesnt on choke neither, could i have put the piston in wrong or the ring on wrong the ring was pinned and i thought i put it in right but couldnt see if ring moved as i put it in the cylinder.i did turn the piston/ring assembly a bit while in cylinder. can you help me.

Chainsaw stalls Chainsaw is 4 years old and has a history of moderate use. After I ran the saw about 1 minute on plain gas (grabbed the wrong gas can – ouch) the chainsaw sputtered and stopped.

It didn't seize, and the pull starter never became more or less difficult than normal. The engine would continue to start if I pressed the prime bulb and engaging the choke, but stall again after 10-20 seconds. The temperature that day was about 50 degrees F and I was running the saw with the “cold plug” installed (per warm weather running).

When it refused to keep running I did the following:
Flushed the fuel tank (that's when I saw the gas had no oil in it).
Ran hardware wire through all of the fuel lines.
Replaced the fuel filter and spark plug.
Cleaned the air filter with a nylon brush and compressed air.

Same behavior (start then stall in less than 20 seconds). I made at least 20+ attempts to start it.

I removed the carburetor and, though it looked perfectly clean, I took off the top and bottom covers then sprayed everything with automotive carb cleaner and blew out the passages with compressed air. The gasket and diaphragm looked new. No pinholes in the diaphragm when held against a bright light. I reinstalled the carb but got the same behavior (start then stall in less than 20 seconds). I again made at least 20+ attempts to start it.

I disassembled the short block and saw that the piston has some slight scoring on it. The ring is clean and I verified that the piston ring has .001 clearance between it and the piston ring groove all the way around with the ring held tightly in place (I was thinking that the piston might have become deformed if it did indeed get too hot when run without any oil premix).

The cylinder wall has no scoring and there isn't any signs of melted aluminum anywhere. The crank is clean as was the inside of the crank cover.

I reinstalled the crank cover using permatex non-hardening gasket goop and torqued the cover bolts to 10 inch pounds. I reassembled everything else per the exploded diagrams in Echo's “parts manual” for the CS400.

During assembly I took note that both the carb gasket and intake boot look like new.

Still the same result: press prime bulb once, engage choke, pull a few times and it starts but stalls after 10-20 seconds.

I'm stumped.

ANSWER : Not sure what to say other than its fuel starvation, if not already done replace the fuel filter in the tank, if no better i would suspect a massive air leak, so replace the crank seals, if there is no primary compression in the crankcsae fuel will not pull through the engine, good luck.
