Saw issues

[iskiatomic]

While I am not a small engine mechanic, I am fairly handy. I am having issues with my Husqvarna 372XP chainsaw. The saw will start and run like a champ, go through a fuel load, refuel, and the saw won't start.

I'll let the saw sit, go stack or split or something, come back to the saw in 20-30 minutes and it fires right up. Runs through that fuel load, and repeat.

New plug, air filter, fuel filter. Running good fuel and mix.


I am stumped here, please help.

Tough to say if I'm not there. My gut feeling on it though is a faulty ignition coil. It's killing the spark when it's hot. Of course, the only way to know for sure is to clip in a good park tester and test it while it doesn't start. It could be a lot of things though. Test the spark and go from there.

Still getting spark when saw is hot.

does that saw have the winter setting on it?

Ok. Next things I would look at would be fuel quality (gas-oil mix and water content). Cylinder walls. Pump diaphragm and interior carb condition. Test the tank vent. It's sort of a routine I have whenever I work on a saw. If I don't find a fault in any of these I would then do a leak down test to check the seals and intake condition.

Are you using choke to restart it when it's hot?

 

[iskiatomic]

Not sure on the winter setting.


No need for choke after hot.

What happens if you run it for 1/4 tank shut then it off...will it restart? Could it be flooded? Ever try getting into a position where you could totally depress the trigger to restart it?
