Bax,
Thanks for the info, the carb is the one that came with the eng. when I bought it new in the early 90's, there's not any slop in the liner & piston,( maybe 1/2 of gal. of fuel ran through it) now that I remember I had similar problem's back then even sent it in thinking there was something wrong only to have it returned with them saying it was fine. The more I ran it the better it got with alot of tweaking. I'll keep at, just recently got back into the hobby, glad I didn't sell off the stuff. Are parts still available for this eng.? Also how does the new G34 stack up? If it screams anything like the S29 does when it's running properly, might be a good upgrade.
Thanks again,
Robert
