Carb tunning/mod question

Rick i wish you hadn't. always looking for ideas.

Today's plan is to get a much larger vac gauge, install a 2.5 power valve and go from there.

crackedback, 40* of total timing was my best MPH which it 22 degrees Initial. with my new vac gauge, i will us it to fine out how much Initial it likes and then try to restart it. then i know how much initial to pull out.

There was a thread....i thing on here, that told how many thousands the slot was = how much inital you had or how much of the slot needed welded up. I used this when i re-curved my distributor for my 340 but cant find it now........

fishy68, in my mind, lean the idle and transition circuits out is a good thing :???: But messing up a good working carb is the last thing i want to do!!!!!!
