Default Re: Compression test - pressure 2 high???

Not necessarily the wrong cam, simply building cylinder pressure sooner, so my guess is low rpmn short duration...but I'm no cam wizard.

As for mixing your fuel, thats a no no...run the straight 100ll and try it, otherwise id say youre closer to 93 than the 100 you're shooting for...mixing doesn't work linearly like you'd think it should. I assume you've checked your timing/dizzy to make sure it's no doing anything wonky like adding too much advance?
