Saw Only Runs WOT

[Aics]

Old Husky 372XP, saw starts on cold on choke and will idle a few seconds and die. Can't restart warm unless holding WOT. Saw will keep running, but idles rough, if holding the throttle wide open. It does NOT rev up. Carb adjustments have little to no impact.

Replaced fuel filter, air filter, fuel line, tank vent, tried another carb, checked muffler...

I'm thinking I have an air leak.

Thoughts?

I think that you are probably right. Just test... Why guess?
