Capone Posted March 19, 2005 Report Posted March 19, 2005 (edited) '03 Shee 370cc K&N Pods Boyseen PowerReeds CoolHead - 18cc (110 octane) Wiseco ProLites FMF Fatty - PowerCore's I'm @ 500ft elevation. I was running 330 mains, 30 pilots, and airscrew 1/2 out and needle clip 2nd from bottom, it was running good. I changed fuel from c-12 (40:1) to 110 leaded pump(32:1). Then all the sudden it started popping in the powerband. I switched to 350 mains, raised the needle 1 clip, and it just plain shitty, popped, no power, couldn't even hit the powerband. I switched to a 320 and it was the same. I was wondering if the 32:1 was too rich with the lead? I know c-12's leaded also, but I was told c-12 has around 1 gram/gal and most other 110+ octane have close to 15-30 grams. I'm sure this "Clark 110 Race" is more towards the 30 mark. I'm going to run c-12 tomorrow to see how it does. If someone could maybe give a jet range/needle position.. I would appreciate it. Edited March 19, 2005 by Shee K Quote
