Timming changes on its own??
Hey guys, latley my car has been running bad and popin threw the carb andit was to rich and all that, so I figured it was a combo of timming and fouled plugs cause my valve guides are bad and my plugs foul out alot. So I change my plugs and I go to check my timing and its at 3degrees. now I had it at10-11 so how did it get down that low?? I was completly amazed it was even runnin with that little of timing.

Distributor clamp not tight first thought. Simple thing to check. Most likely cause
Also check the vacuum advance if you had it connected to manifold vacuum. Vacuum diaphram could have a hole.
Check the advance weights also. Make sure they aren't sticking. Now, you should not be getting any mechanical advance at idle....but I've seen lots of cars that had too light of advance springs installed and they were getting advance at idle. Not good.
