I'd like to pick some of your brains on my new saw.. Ill try and make this brief.
I picked up a 576xp non at off my buddy a week ago, saw has a new meteor piston and carb kit. It was built from several saws.
Saw ran great first tank, we cut a bunch of small 12" wood with it when I picked it up.
Went cutting yesterday and it ran great for the first 10 mins, then after cutting some big wood it seems to not want to go back to idle, seems a bit lean to me. After cutting it slows down to almost idle but often the chain keeps moving, fattening up the bottom fixes it till I cut again and then it goes right back to lean.
I tuned the saw in the wood it 4 strokes nice out of the cut and is slightly fat while cutting, perfect for break in.
Plug is golden brown, everything looks fine.
Saw failed a vac test and passed a pressure test this morning.. Check it with soapy water and couldnt find any leaks.
Checked the cylinder and case bolts, they were tight. I resealed the oil pump bolts and also checked the impulse line and intake.
Everything checks out fine on the saw, but it seems a bit lean only after I get it warm and cut big wood with it.
Question is where would you guys look for problems?
Crank seals is my thought.
Any help would be great..
