dajogejr Posted January 15, 2007 Report Posted January 15, 2007 10mm cubrockets k and n clamp ons v force 3 39mm pwk -- 160 main, 45 pilot 1000 feet above sea level. Similar... my old motor, 4 mil, Shearers, K&N Pods, 35PWKs, 500 to 750 feet above, I ran 150 mains, 48 pilots, CEL needles, mid clip. When it was cold @ the dunes, I opened my powerjets to 1.0 turn out to be on the safe side...ran good!! Quote
FasterThanU90 Posted January 16, 2007 Author Report Posted January 16, 2007 hmm im at 175 at sea level plugs are a little dark felt like i had a flat spot on top tho tried sum 110 mix a little maybe that was why with not enough time advance Quote
locogato11283 Posted January 16, 2007 Report Posted January 16, 2007 you need to go down with your mains. how dark are the plugs?? putting a higher octane fuel in isnt going to fix the problem.. Quote

FasterThanU90 Posted January 17, 2007 Author Report Posted January 17, 2007 "you need to go down with your mains. how dark are the plugs?? putting a higher octane fuel in isnt going to fix the problem.." yea it is running a little rich wanted to see what everyone else was running to get a ballpark. plugs arent that dark. i kno i was saying that because of the higher octane thought that was causing it to act up on top is that just beacause of not enough timing?
