Husqvana 136 won't start
« on: June 11, 2020, 02:24:34 pm »
My Husqvana 136 suddenly died and won't start.
I cleaned the fuel tank, checked plug is sparking, checked carb diaphragm.
It will start for a very brief time only if the throttle is fully open. Then it dies.
I replaced the carb  a couple of years ago.
Halfway through a job.

Pull muffler check for scoring or stuck ring.  Need good compression, gas, spark. Check all 3.

Thanks for the advice.

Compression is 135psi.

I've attached a photo of the piston. Doesn't seem scored.

Muffler is oily; is that normal?

I ran it for longer today, starting with full throttle again.
It smoked quite a bit, misfired and sounded tinny.
Died when throttling down.
Adjusting jets made no difference.

I removed the air filter and ran it the same way. Petrol sprayed out of the carb. Is that normal?

I've ordered a new carb from Hong Kong. Will take a month to get here though.
