With a base timing set at 20-25, (second notch on the pulley) then add 40 degrees advance, thats a total of 60+ degrees total timing when you combine the two. So your timing is advancing way too much and will LOSE power in the lugging rpm.
You want a total of 40, or around a total of 40, but not much more. On my Super H, I had a 40 degree dizzy, it fluttered under acceleration, it was very lazy under power. I went back to a 23 degree distributor, it was a totally different animal! It revved up quicker, it idled alot better.
I want my advance timing in, before I hit rated pto rpm, so when the load is applied,, everything is there, already waiting for the load to be applied, if its still searching for timing from too much advance, it will float the timing advance and the rotor will rock back n forth,,, hunting I call it,,,
With it locked into less than or around 40 total degrees, it will set itself faster and lock in ready for a better peak power range for a certain rpm range.
Now, if you have high compression, lets say you run a compression test,,, and its less than 200 psi,,, throw away the race fuel, its not helping to build torque. Only one fuel combination has worked to make power for what I have done in the past. A mix of E85 and 93 octane pump gas. Its also about 4 bucks cheaper a gallon. ChadS
