Husqvarna 445 won't stay running

[Hunter Dan]

Got my 445 pinched in a tree trunk and after finally wrestling it loose it only runs for a second and quits. Starts right up every time but won't run. Quits before I can get my hand on the throttle. Any ideas?

Start off with the easiest, dumbest stuff first. Fuel in the tank? Chain brake disengaged? After that, I would take off the clutch cover, bar, and chain. See if getting pinched caused any sort of damage under there. Anything bent, cracked, or otherwise abnormal looking?

Possible you could have ripped the intake boot or impulse line while pulling it out.

Perhaps this would get more traffic in a different section ?

Also check the primer lines.

Not sure if its construction is similar to a 350, but you may have pulled the screw out of the left av spring. It tweaks the handle so the throttle linkage won't work. Or possibly you tore the intake boot

I was thinking the same. I removed it and found no tears. I will try a low-pressure test and see if there are any pin hole leaks.

I am new to this forum. Which section would be best?

It was relocated to the chainsaw forum already to get more views.

Damaged crank seal on clutch side causing air leak!

How can I tell if crank seal is damaged or not?

Can you check the compression?
