Ok mr Spock! Actually, I was thinking similarly, that’s why I wanted to try. It went from no start to one pull start. And I saved all the originals from other machine recently, so might as well give them a try. You’re right, if I need new seals all around, much easier just to go new.just thinking logically. i have dealt with many damaged seals and if you can't find a good used one off another machine it generally sucks to spend $20 on a seal kit when you can get a complete carb.
