'60 timing/idle performance

[Matt F.]

My '60 has a newer Edelbrock carb, and NOM 350. With the timing set to 8 deg. advance, it idles nicely. When I pull sharply on the throttle linkage, it gives a "huff", hesitates like it's not getting any gas, and if I release the linkage quickly it goes back to a normal idle. It looks like the accelerator pump is working fine, I can see the gas coming out. If I very gently and slowly pull on the linkage, the hesitation is minimal and rpms go up normally. This is probably something real simple, but I'm not figuring it out...help!

Matt, look for a vacuum leak. I'll bet it's at the base of the carb.

Loosen the Dist hold down ,pull sharply again and again as you move the Dist to advance or retard a little at a time till the engine dose not stubble , tighten the hold down -- your done!!
