Back at the end of 2016 I mentioned buying a Thumpr Cam for my build. 74 302 .030 over, Duraspark, New Painless Harness, 3G upgrade, and GT40P heads. A few people said to go for it and one person said "DON'T DO IT". Well I should have listened to him. I have a new Edelbrock 1406 carb and this thing won't idle after getting warmed up to operating temperature. I have plenty of torque and top end power but it just won't Idle.
Things that I have tried:
Set the Idle Mixture screws per the Elelbrock's book
Advanced the timing from 10 to 15
hooked the vacuum advance to Manifold vacuum
Changed the location of the squirt rod to the middle hole
tried the choke on different settings
New gas filters and made sure the gas lines are not getting hot anywhere
Engine temp stays at 190
Any recommendations on what to try next? I'm about to head out there now and pull this POS cam out tonight. Thanks everyone
