Like I said I clipped the little tits off so I could get more adjustment out of my 346xp. However I can screw it in forever and it never bottoms out or seats or even feels tight like the metal is possibly seating. Am I able to remove the plastic caps altogether? I’ve had the carb out a few times to clean with my ultrasonic cleaner but can’t get it tuned correctly. I just bought a tach to time it perfectly. I’d like to give it another shot before spending $65 on a new carb.
