You need to pressure test the carb, it sounds like the inlet needle is leaking, thet are rubber tipped and this does wear over time. a pessure test will show you very quickly if it is the needle.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

This can be caused by normal variations in air pressure that occur due to changes in temperature throughout the day and night. This is particularly present in areas that experience more drastic changes in day/night temperature.
One of the major reasons why an engine leaks oil after an oil change is from rotted engine gaskets, oil seals, or bad connections. If you get under the car, check the oil pan seals and oil pan drain plug. You`ll then want to check the timing cover seal and valve cover gaskets to see what shape they`re in.
The fuel tank on your chainsaw is a plastic reservoir that stores fuel. The plastic can occasionally become cracked, and when this happens, fuel can leak out. There are several places on the fuel tank that can cause leaks, such as the grommet, the gasket, or the fuel cap.
If your chainsaw is using too much bar oil, you may need to clean the bar and chain and rid it of built-up dirt and debris. You can do this by spraying a degreaser onto the bar and chain and letting it sit for a few minutes before wiping them clean with a rag.
Common causes of oil leaks include degraded engine gaskets, leaks from the oil pan, or improper or worn out seals. An oil leak also can be caused by a loose or missing oil pan drain plug or deteriorated valve cover gaskets.
The first is engine oil. The chainsaw shown here has a two-stroke engine, so it needs two-stroke engine oil mixed with the fuel to help cool and lubricate the moving parts inside the motor. The second type of oil, called bar and chain oil, is for lubricating the chain as it cuts.
There is an easy way to find out if your engine`s head gasket has blown. Simply check under the oil filler cap. If the gasket is not damaged, the inside of the oil cap will be mostly dry. If you discover a milky brownish-yellow substance that is similar to the thickness of a milkshake, you probably have a gasket leak.
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.
Add a small amount of fuel stabilizer to stored fuel and your lawn mower, snowblower, rototiller, chainsaw, generator and vehicle will start easier and run better. Fail to use fuel stabilizer can mean poor performance or an engine that fails to start at all after several months of storage.
Are chainsaws supposed to leak oil? To a certain extent, yes. A few drops are normal, as it`s most likely residual oil from the chain. But if there is a huge puddle or if the oil obviously isn`t coming from the chain, then something is out of order and you should investigate further.
Use a flashlight to check underneath your car and around your engine – telltale drips might lead you right to the problem. There are several common locations for oil leaks in your car, including: At your oil pan gasket. At your oil filter or drain plug.
No. You should never use WD40 as chain lubricant since WD-40 is NOT a true lubricant. WD40 is primarily a solvent or rust dissolver.
Naturally, the chain of your chainsaw will need to be oiled well to function perfectly. To make sure that it functions well, grab some WD-40 Multi-Use-Product. WD-40 works great for both – rust prevention and lubrication.
ATP is a universal fix and an excellent choice to stop oil leaks and to undo minor damage to the fuel system. This formula provides a safe way to stop oil leaks in both diesel and gasoline engines with plastic or rubber shaft and valve stem seals.
The short answer is yes. Head gasket sealers can temporarily fix a leaking head gasket, but they`re not a permanent solution. These products last a little while and can only do so much; eventually, the wear and tear will need to be dealt with for your car to run properly again.
Symptoms include: over reving, overheating, stalling on acceleration, failure to idle, and worst of all, an engine seizure if the problem is neglected. When an air leak occurs, it often puzzles users and even some saw shop technicians because the symptoms of an air leak are varied.
Engine oil leaks are one of the most common causes of engine damage. They cause rapid deterioration of the engine and result in expensive repairs. Worse yet, engine oil leaks pose a safety threat. They may lead to the loss of control of the vehicle while driving.
One of the easiest ways to fix the leak yourself is to use a stop leak additive or high mileage oil blend. Such products can soften and condition your car`s rubber seals to stop and prevent further automotive leaks. It may take up to a few hundred miles of driving before the leak is completely sealed.
Generally, oil leaks from oil pans are rare since they are tightly fitted. But any sort of damage or a loose-fitting pan can cause an oil leak. An oil leak can also happen if the oil pan gasket gets worn out, just like the worn-out valve cover gasket. Well, these were the common reasons behind oil leaks.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

I was using the saw as a chain saw last weekend to cut up an old tree stump when the chain came off. I don’t know how to access it to put it back on and don’t have a user manual. The saw belonged to my late father and I don’t know if he even kept the manual.
ANSWER : You will have to remove the cover on the side the chain bar goes into. There should be one or two nuts holding the cover on the side. The is also a chain tension adjuster you may have to loosen to put it back on. Make note of the direction of the teeth on the chain. It is an directional chain. The tension adjuster is usually a flat head screw on the front side right beside the chain bar.Unless it is a really old saw, manuals are available from most manufacturers for free download. See if you can locate a brand name and model number.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
ANSWER : Hi owjbhend…
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.
Below is a drawing of how to route the fuel lines.
