Question on Timing (easy I think)

I took the old goat out after sitting in the garage for 5 years and it really runs pretty good. The one problem is that it starts hard when it warms up. I remember turning the distrubitor on way or another to cure this but cant remember. I also remember getting some ping due to the cheap fuel if my memory serves me right Can someone help ?
Thanks Dino

When you turn the distributor, you change the timing. Since both symptoms can be fixed by RETARDING the timing, and a Pontiac distributor turns CCW, you must turn it CCW to retard ignition timing. I would use a timing light, and see where you are at now. Retarding the timing might fix the problem....too far will also effect the performance negatively. E

welcome Dino....if you turn the vacuum advance diaphragm towards the motor you are advancing the timing, sounds like you need to turn it a touch back toward the firewall to retard it, could also be heat sink on the starter and wires down there make sure they are as far away from your exh. manifolds as possible. if its an older build on the motor you will want to run at least 93 and may need to mix in race gas to get to 101 as it will have 10+:1 compression.

SOMETHING NOT TO DO: Dont stand the springs on end, under a lift, with a car on it. Let the lift down to compress the spring. Tie the spring with coat hangers. And remove to install in the car......."someone" used to do this in the early 80's......

Eric, I almost never need to remove my coil springs when I adjust my timing. Sometimes, yes, but not often.
