Setting base timing for performance cam

[EagleMark]

I am running about 52* total timing and the engine loves it. Like the old saying goes, give the engine what it wants, not what you think it needs.

You sure? Are you super rich? Something is wrong? 50* is nitro top fuel timing and their spark plugs melt before the end of 1/4 mile but magneto will spark to anything at that point...

I have no rich running trouble now. That's for sure. I even added around 2 turns out on the mixture screws. Note that my fuel economy is about the same. So I gained very noticable power for no loss in economy.

I did all the tuning after weeks of research and discussions on other forums, lots of trial and error, lots of testing and hard pulls, etc.

I am going to say his dampner has either slipped or he has the wrong one for his timing cover.

My damper has not slipped. I used a piston stop to degree it. The timing marks line up correctly.
