I use haggertys. so far so good.
but I haven't had to use them, and hope I never have to.
I sell insurance for Farmers Insurance and don't like the "book" price they and almost all other insurance would use.
I have used carb cleaner and sprayed around the intake, but w/ the fresh paint I'm not sure I would do that. Maybe wd40? if your intake is leaking should kill the motor when you spray around intake.
