69 Camaro, 350/300 original motor, Quadrajet carb
Engine and trans rebuilt about 1,000 miles ago, mild cam, 10/1 cokmpression, rebuilt and restored carb, it's never quite idled correctly. New points, plugs, wires, dist cap, condenser and rotor, fuel filter, fuel pump, vacuum advance.
In neutral it is set at about 800, drops down to about 550 - 600 when put in gear. Played with the idle circuit today, pulled the screws and blew them out, readjusted. Idle is set at 11 degrees adv, total advance is 31.... any higher than that and it pings.
Played with the idle speed and it seems "happy" at around 800 static. Has a slight
hesitation at initial acceleration (about 1/2 of a second), and then it just runs like a brand new motor. Doesn't have the greatest acceleration at low end but not sure what to compare it to??? Seems like it should have a little more "umph" at takeoff.
Thoughts batted around today with Farmboy are:
- Carb rebuild? - It's fresh, but maybe the restoration company I sent it to didn't do it properly??
- Torque converter? - The trans is not original, but it is from a 69 Camaro. The transmission shop I sent it to for a rebuild put a torque converter on it, but I don't know which one they used
I hate to mess wit hit because it runs so good, but it would be nice to see a little more power from it at lower RPM's and get rid of the loping at idle when in gear.
