Husky 55 hard to restart when hot

[PA. Woodsman]

What would cause my Husky 55 to become darn near impossible to "restart" once it has been running and is hot? When I try to restart it, it'll run for 1 or 2 seconds and shut off; I took it to the dealer and he had very little explanation for it. He said "it's almost like vapor-lock" and stuck his finger in the gas tank and said the gas was "extremely hot" but offered no suggestions on what to do to solve the problem! The saw is about 8 years-old. Any suggestions would be appreciated!!

are the motor fins clean and clear of debri or dust?

maybe it's over heating?

proper fuel mixture?

Yes, I am wrong; he DID say to clean the fins out, which I did. And I have the fuel mixed like I always do. Very puzzling...

i just read this at some forum about chainsaws not starting or hard to start when hot:

It has been my experiencethat if an engine wont start when hot that you may have bad crankshaft seals. A quick test for this is to get the engine nice and warm...2-5 min. From the upright position at idle, turn the saw on its side... if the RPM's go up you have bad seals. The saw is allowing air to flow directly into the crankcase effectivley causing a "lean-out" and will ultimately cause piston/cyl damage.

just another thing to check out.

here's the link to it:

Thanks I will try that next time I'm using it. I recall this saw aslo took a "tumble" (as did I) 3 1/2 years ago when a ladder collapsed and we both went down about 14 feet; I had it checked out back then, but perhaps that is playing into it also. Thanks again!!!

Husky 55 Rancher

My son recently bought a 55 Rancher to cut firewood. He had the same complaint. After alot of checking we found out that Husky has a bad batch of fuel filters. Something about the double check valve in the filter. The dealer changed out the filter and it has worked fine ever since.

I'll talk to the dealer about it, but I could see your son having this problem with the saw that he just bought, but mine is 8 years old; I would think that if that was the problem it would've happened years ago? It just recently started, but who knows-it couldn't hurt to have the fuel filter changed. Thanks for the reply!

Just about every saw I ever had didn't run quite as well in the summer as in the winter. Boiling gas, vapor lock and all the other crap that can go wrong. I never wanted to screw around with my carb just for summer cutting so I put up with a saw that won't idle very well and won't start hot very well (I use Husky and J-red). Anyway, I swear high octane gas helps, but not a cure-all.

My friend at the stove shop also recommended this; I'll give it a try. Thanks!

I had a similar problem with a Stihl 029 a couple of years ago. The repairman took it for 2 weeks and tried everything he could think of without success. Finally changed the spark plug and it has worked great ever since. Apparently it had a crack that opened as it got warm. Doesn't cost much to try.

I would be inclined too think crank seals as others have said. The usual tell tale is when the saw starts fine cold and idles fine or slightly high and then slower and slower as it warms and probably won't idle hot.

Husky Troubles

Thanks for this thread. I'm having a similar issue. Starts OK but once warm I have problems. If I don't keep it running above idle, it'll die. However, it starts up again as long as the throttle latch is locked to start the saw as if it were cold. I'll try the troubleshooting advice too & see if I need to ask the shop for a diagnosis of the crank seal.
