Husqvarna 55 not responding to tune

[jakethesnake]

Has H L and T. Turning them does nothing noticeable. Where to go from here. 2003 all original owned since new. No other problems ever. Cut all my firewood with it this year and it’s seen a lot of work. Never put a carb kit in or done anything to it. Just never ran into this. Any suggestions. Yes I’m a noob

Probably a Zama carb with limiters. Have you tried to remove them?

Nope. No response Think ima park the saw and use a different one this afternoon. Working on 2 big leyland cypresses that blew down all tangled in a knot

Hmmm, check for an air leak.

Rebuild the carb. Sonic tank in Berrymans carb cleaner.
Make sure to remove the needles. New kit.

Not running lean but not ruling that out

I've got 2 55s and 2 50s, the only place I've had an air leak was a cracked fuel line where it exits the tank and a clutch side crank seal. People say the impulse grommet is a weak point on those saws but I've never had an issue with those.

My thoughts

You can get a HiPa Chinese carb for about the price of a kit. I've had one on a 55 for couple years. It's a walbro clone. It's worked flawlessly so far.

I’ll play with it next time I get a chance. Needed to get done what I needed done today. I’ll revisit soon

Check your fuel line.

 

[Woodwackr]

Check your fuel line.

And filter

 

[jakethesnake]

Check your fuel line.

Will do buy fuel line was replaced not too long ago. Will also check filter but I usually keep up with that

 

[mrxlh]

My 55 went from running fine to acting abnormal after just refueling. When I finally got around to looking at it the fuel line had like 5 pin holes in it.

Ok. Started saw this morning. Shut off. Closed all needles on carb. Reset. Runs fine even after 10 cuts or so. Idles…. No clue.
