My 041 AVE super with 048 piston Idles erratically like it revs up and slows down revs up and slows down and when I blip the throttle it idles fine for a few moments and then revs up then up and down. Ive set the saw up 4 times already (carburetor) perfectly and it does the same thing revs up then
goes back to idle then revs up then idles down again. I can leave it idle for 10
minutes and it wont quit whats the solution?

That's what mine did (041.. not a super)... gasket between the carb and case was shot. Bigtime air leak.. if you let it go the saw will eventually not idle at all. If that doesn't work, you'll need to consider a carb job, not hard to do if you're handy.
