The quench should be helping you. A huge part of the equation is the mass the engine has to move. You're making it easier: light weight, with gear, and with convertor. So bring it. Watch the plug porcelain with a lit magnifier for any signs of piston material. Also be aware of carb tuning each time you make a timing change. You don't always hear a problem. But we run 91 crap with 10% ethanol in the ground here.

Thanks for all the replies ! A little update, I weighed it at the dragstrip last SAT., it weighed 3278 w/ 1/2 tank of lawnmower gas. Didn`t get around to running it, want to put some miles on it first. It seems to like 21 initial, think I might try bringing the total in a little sooner . Thanks again , bob
