OK collective having trouble setting up a "Members" 70 318 after rebuilding the Carter BBD 2 BBL. Wasn't getting fuel to the carb from the new tank and sender so swapped out fuel pump. With a little priming car started up running but was rough and surging. RPMs fluctuating between 850-950, Vacuum gauge reading between 15-17 hg but not steady. Set idle - set mixture then went to set timing....initial was running over 25 with the advance disconnected. Backed off to 10 degrees but RPMs dropped to 500 and then stalled out. Now the car wont idle at any advance even with the idle screw all the way in. Only way to keep it running is to position cold idle cam on step 2. Timing mark is bouncing on damper and not steady. So possibilities?
Stretched or jumped timing chain?
Stuck mech advance on dizzy?
Carb float level
Low fuel pressure (fuel filter doesnt fill right up)
Burnt valve?
So surging rpms
Bouncing timing marks
Fluctuating vacuum
Wont idle
Huge initial advance reading
Feels strong at higher rpms
Nothing out of tpipe
Ran when parked
Only carb has been changed all other ignition components unchanged
New fuel tank/sender
Opinions please!
