Just want to say thanks to springdrl. I just adjusted my cultch as per your inst. Works great now! Also changed the main jet to 117.5, and turned the pilot screw out another 3/4 turns. Starts a lot better, stays running without the choke after 2-3 mins., and runs smother. Still a little popping on decell, will have to get next size up pilot jet. Thanks again for the clutch info.
