You need to replace the coil but first try to change the sparkplug and see what is happening.

I have a Homelite Chainsaw 45cc Power Stroke. Model No. UT10946D. The chain brake is always applied. Brake lever will not latch in the released position. I've disassembled it and do not see anything...

I have the same model (ut10946d) and used it for less than 2 tanks of gas when the chain froze. I noticed it was slowing down and it seemed like the chain brake was not disengaging and staying in the "unlocked" position.
I took the tool apart today and found that the band that rubs on the clutch to stop the chain was dragging on the clutch because it doesn't disengage all the way. The heat from the friction melted the plastic parts around the clutch housing and crankshaft. So now I have a chainsaw that I bought new, used for less than an hour, and is now junk due to poor design and/or product control.


My solution, call homelite and complain about it, maybe they'll stand behind their design flaws - but I doubt it.

Will not start

That seems to imply that the check valves in the primer pump and in the fuel pump section of the carburetor are bad or the air pressure just forced by the valves. The line without the filter is the tank return line from the primer pump. The primer pump is supposed to pull fuel from the fuel filter into the carburetor flooding all spaces within it it, then passing out to the primer pump and from there, back into the tank. Does the primer bulb fill with fuel after several pumps? The first try may take longer because you forced all of the fuel out of the carburetor with the air pressure. Make sure all of the carburetor fasteners are tight. It's possible that you have injured the diaphragm in the carburetor lower chamber when you blew air into the line. Go to: for a 12 page article on Walbro carburetor theory and troubleshooting. Make sure the spark plug gap is set at 0.020". Hope some of this helps!

Chainsaw won't start when warmed up

Coil is possible, change the plug (cheap insurance) and try it. If problem persists try this shortly after it quits.
Ignition Coil Test by
You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode.

An index or business card is good for gap tool. Remove the plug, rotate until magnetic attraction pulls coil and card tight to flywheel, then tighten coil screws. Rotate flywheel until magnetic attraction eases, remove card, rotate a couple of revolutions and ensure nothing drags or contacts flywheel.

Homies are bad for clogged fuel vents too. When it begins to sputter roll it onto side and loosen fuel cap. If ti smooths out and runs properly it has a clogged vent. HTH

Homelite chain saw quits in 15 minutes

Why are you not standing on the help desk where you purchased this? If it starts to sputter then dies It is probably a plugged fuel tank vent. When it begins to act up roll the saw so the fuel cap is up right and loosen it a little. If it smooths out and runs correctly you just vented the tank and that is where the problem lies. If it suddenly stops running with no warning it is most likely an electrical problem. If you repair either of these problems it may void your warranty. Why not make Homelite repair or replace it? If offered a refund I would not purchase any product by the same manufacturer. At best their quality control is lacking. HTH

My 18in homelite saw starts ok, cuts fine but, when you shut bdown to refuel or take a short break, (over 5 min) it will not restart till it cools down or about a half hour. Thanks

Loosen the fuel cap when you shut it down tighten it before you restart. If this fixes it you have a plugged fuel vent. HTH

Runs well untill it gets hot. then cuts out

If it's the little xl model, it's probably the ignition coil breaking down when it gets hot and therefore it can't and won't be able to handle a load. Also, scarred pistons skirt or rings could also be some of the problem here. Make sure your mix for a Homelite saw is 40:1 not 50:1 like most saws are. Homelite seems to run better with a heavier oil mixture. Good luck.
