Husky chainsaw only runs with choke on

Long story short...

My Husky 55 rancher ran great for 5 years until I burnt the top end on my chainsaw one lovely evening. I put on a new ring piston and jug, but it wouldn't run right. Have since put on a new...

Fuel line
Fuel filter
Air filter
Completly rebuilt the carb twice
Spark plug
Checked the gas vent
Carb mounting plate and gasket (stripped the old one)
Cleaned the Muffler

Now it only runs with the choke on. And runs pretty decent, at that. The only things left that I can think of are either I should just buy a whole new carb all together. or some people were saying if I burnt the top end, I probably burnt the bottom end seals. Would this cause such behavior? Do either of these sound like they could be the problem?

I've been pulling my hair out over this. I would really appreciate any help. Thank you.

Ya the crank seals could cause it to run lean. When you choke it you cut down the air intake.
Sounds like you got the carb and intake covered.

Crank seals is the place to look. Take a good look at the crank bearings while you're there too, they can get damaged when the saw gets toasted too.
