Add idle timing, leave total timing where it is. It will take more fuel with more timing.

I am running 94's in my 1000 on my 512...Also, what idle bleeds are in it and HS bleeds are in it. You should have #70 idle bleeds, and #27-32 HS bleeds...I run the #27-#28's and it is dead on.


Idle bleeds are #76 and the HS bleeds are #32.
I'll add more idle timing and see what it does. Thanks for the suggestion!


Change idle bleeds to #70-#71 too...Then start working the HS bleeds down while watching plugs.
