Dumping the FBO timing advance plate.

I tried one of those FBO plates and sent it back through paypal. They are not accurate at all, as others have said. I welded mine up also.

I bought a plate for my distributor about a year ago.



I set mine at the 14 degree mark and got 15 degrees of advance. Initial at 20 degrees, total went to 35. That is close enough and it worked out quite well. Yeah, I could have welded up the slots but this was far easier to tailor the total timing in less time with less work.
