I’d be giving it a vacuum- pressure test, sounds like an air leak.Hi Steve, they are set in the middle of the 3/4 turn allowed
If you have an old bike pump around with a psi guage on it, you can test for leaks that way. I’ve got more than one saw that I had to strip down and dunk in a bucket of water to find a small leak.Yeah, if nothing else I'm getting fast at removing the carb! I got it to run right for about 10 seconds then it stopped. I've got the new carb soaking and I am going to put a kit in it. If that doesn't fix it I guess i'll suck it up and buy a vac tester.
I’m with the rest of the posters on here. Check your fuel and impulse lines to the carb. If the carb has been rebuilt all it could be otherwise is muffler screen choked up or crank seals usually due to a shot bearing. Since it’s a clamshell motor you may be able to pull the flywheel off and clutch check for play, and if so replace bearings and seals. They are not that hard to replace just time consuming. If it’s been sucking air your piston-cylinder may also be shot so you would want to check for that.I'm working on this saw and no matter what I do it will only run on choke. I rebuilt the first carb- no change. I ordered a used oem replacement. Same thing! I checked the fuel line and filter and they are fine. What is going on here? Thanks
