Ok question guys... will the vac advance work at WOT? Reason I'm asking is bc when I raced it I only had 14 deg at idle. And when I pulled my vac hose off the dizzy it was only pulling 20 max with the limiters I had in it. I think I was going all the way down the track with only 20 deg timing.
vac advance will have 0 vac at full throttle. If you are saying that you have only 20 degrees TOTAL, that's why your rich at the track. more timing(32-38 ) will make it run much better and lean out the top end charge.
