I have been rockin the same dizzy for quite a few years.....locked out. A week or so ago I decided to roll a few more degrees into her to try and make mo powa.
I jumped it up to 42 on the light at idle.
For what ever reason I decided to give her a little gas. Pretty much immediately it started pulling timing out. Looked like 4*....it was at least 3*
I have often heard that an hei will loose a little timing with RPM.....but I never would have thunk 4 degrees.
Everything APPEARS to be locked......it has a vac can.....but I welded it in place so it cant move around.
Is that " normal" for it to be loosing that much timing??
