Re: 42 miles of He.....
LOL been there doing that with the skyhawk 66cc slant head. I just got a bgf motor and Iam trying all the pointers Ive picked up here like lapping the head and jug, port matching, jet soldering and using a expansion chamber before I install this motor. I also buffed out the exhaust port and used copper coat on the head and exhaust gaskets. I hope this helps my odds of getting a good motor this time. If this helps Ill try it on the skyhawk next. Thanks for all the great info on this site got to love it.
