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 :
If the carburetor is clogged, it may only work with the choke engaged, which is not a good way to be running your engine. Cleaning the carburetor and replacing some of the internal parts with a new carb kit is a great way to get your carburetor running properly again.
The two most common reasons a chainsaw won`t idle are a blocked air filter and an idle screw out of adjustment. Other possible causes include: Dirty Air Filter. Idle Screw out of Adjustment.
There are many factors that can stop your chainsaw from running, including a bad spark plug or dirty air filter. There are simple problems: a broken fuel line, bad fuel, wrongly calibrated high-low adjustment screw. Also, more complex issues like a damaged carburettor or an engine compression problem.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking (partial or full) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.
If your bike is only running with the choke on, it`s probably because it`s running too lean. This can be caused by a few different things: All internal combustion engines need three things to run: fuel, air, and spark. If any of these are missing or not working properly, the engine won`t run.
The most common cause of a chainsaw that won`t cut properly is a dull cutting chain. Try sharpening or replacing the chain. Need help finding your model number? The chain may not have the proper amount of tension.
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.

We do not recommend that any type of outdoor power equipment be operated after initial warm-up and with the choke control outside of the normal run position for longer than 5 minutes. Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.
Dirty Carburetor (air+fuel)
If fuel sits in the system for too long, the carburetor (and the engine and fuel lines) can become sticky and clog. Remove the air filter and spray the carburetor with carb cleaner—an aerosolized acetone spray made to remove the gunk.
Why Does Your Lawn Mower Only Run With Choke On? Your lawn mower only runs with choke on because of a problem with the engine fuel-air mixture system, which can be caused by the carburetor, bad fuel, or air leaks. The choke compels more fuel in the combustion chamber to help the engine to turn over when cold.

It’s brand new, when I finally get it started it will run good for about 1 min. or less, and then it dies. I pull the choke out all the way, pull it a couple of times, push it half way in, it starts but it’s like it doesn’t have the power to turn the chain, bogging out and then it dies, I will never buy another homelite product, or recommend anyone else to, this is my second one, the first one leaked gas, Home Depot really should quit selling them, there making you look bad too!!

Chain saw won’t start – pull starter pulley hard to pull?
ANSWER : If it worked fine the last time you used it, then pull the spark plug and try pulling the rope. See if it’s easier or if gas shoots out of the plug hole. I’ve seen this happen when the diaphram in the carb goes bad from sitting over winter. It loads up the cylider with fuel and makes it very difficult to pull the rope. If there is no fuel in the cyliner and it’s still hard to pull, make sure there is nothing binding the clutch/sprocket. I’ve had chucks of wook lodged in there that caused it to bind the crank output, which resulted in a hard pull on the rope as well.

My chainsaw starts when there is no bar and chain on it but when I put the bar chain and side casing back on tighten the chain and pull the starter cord it is hard to pull and then the chain goes loose again
ANSWER : Have you just replaced the chain?If so there is a possibility the chain and drive sprocket don’t match causing the engaging spurs to ride on the sprocket teeth

Have new 450 and is very difficult to start. Lost or didn’t get book. How do I start it and re-start it while still warm??
ANSWER : Start procedure is, push the primer as many times as it takes to 3/4 fill the bulb ( you cannot over prime it ) pull the blue choke lever fully out,place the saw on the ground with your right boot through the back handle, crank the engine until it fires once, do not continue to crank the engine with the choke out ( they will not run on choke, only fire ) push the choke fully home, crank the engine until it starts, blip the throttle trigger to bring the saw to idle, warm engine, pull the choke fully out and push in again without cranking engine, this will engage the part throttle, crank the engine until it starts, blip the throttle to bring the engine to idle.
