McCulloch

Experienced gardeners share their insights in answering this question :
Remove the spark plug (ignition off), then turn the saw upside down and pull the engine through a number of times until fuel doesn’t spray out of the plug hole. If this condition repeats, then the carburetor has a problem with the diaphragm/control valve in the lower chamber of the carburetor. The diaphragm needs to be flexible with no damage. The control valve needle tip must be perfectly formed. Hope this helps!

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 chainsaw won`t start, or starts and then stops and you find the spark plug wet with fuel mixture, it means that the engine is flooded (you will probably smell petrol). It happens when too much fuel enters the combustion chamber, possibly because you have pressed the primer many times.
Remove the spark plug and inspect if it is dirty, cracked, eroded, or damaged. There may also be a heavy carbon buildup or a burned-up electrode. If the spark plug has one or more of these issues, replace it with a new one.
Spark plugs ignite the air-fuel mixture that`s injected into the cylinders. For spark plugs that don`t spark dependably, it will cause an engine misfire that robs you of performance. Cracked porcelain insulators and worn electrodes are the common issue. If more than one spark plug fails, your engine may not start.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
Can a bad spark plug cause a car not to start? Yes. The spark plug ignites the fuel/air mixture inside the cylinder. If the fuel doesn`t burn, the engine doesn`t make power.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.

Check your battery`s charge level indicator, ensure the battery is fully charged. Check the battery is seated correctly in the tool. Make sure the battery isn`t hot. RYOBI batteries have overheat protection built into them.
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.

Chainsaw won’t start
ANSWER : Time to get out your trusty tool kit. Remove the side cover assembly and look at the recoil assembly. You should see a pair of fingers that when you pull the cord move toward the center. If the fingers are there and not broken, make sure they move when you pull the cord. clean them if dirty or have foreign objects (like sawdust) around them. If the fingers are broken, replace them. You should be able to purchase them from your local saw shop.

How does the spring attach to the pull cord after you get it wound back up?
ANSWER : The outer spring should attach to the cord spool in a recess or post. Wedge it to keep it from unwinding, attach the inner cord end and thread it around the spool until nearly wound. Feed it out of the cord port and pull the cord out which winds the spring some more. Make sure the cord can reach full extension without binding the spring (don’t let go of the cord!!), clamp the cord with locking pliers, and fit the handle. Melt the cord ends to prevent the knots from pulling out and be sure the cord turns the engine in a CCW direction when pulled!!! Hope this helps!
