timing jumping off on carbed sbc i've got an 87 camaro with a 1st gen small block chevy in it.
after i drive it for more than a couple miles the distributor cap keeps sliding and retarding itself. i have to get the timing light out and reset it everyday before i drive it again. i torqued the **** out of the hold down clamp. but that doesn't seem to help.
i will say that there is a small leak in the back of the carb. it slowly drips out. i'm thinking that the slippery gas might be getting on the distributor gasket. nbut i'm not sure if that is the problem or not.
i was wondering if any of ya'll had some tricks to help a problem like this?

yea, the clamp i have on there right now was like 4 bucks. i'll try a high dollar one. hopefully i'll have some luck.
do ya'll not think the gas leaking could be a reason also?

I know this sounds dumb.. but make sure that the bolt you are using on your holddown isn't too long. I used one once that would not bottom out before it applied enough force on the clamp to hold the distributor in place.
Very good point. You could try a stud/nut type setup.

yea. thats what i actually did. i used a stud. then a washer. then a lock washer. it still didn't work. its driving me crazy. i pulled the distributor the other day just to make sure it wasn't jumping. and my bronze gears seemed to be in good shape. that means it couldn't be jumping right?

Verdad Gallardo Did you replace the clamp yet? There is a good but slim possibility that the shaft is bent creating a side load that binds up the housing and causes it to jump. with a bronze gear, I imagine that you are running a roller cam?

yea. its a roller cam. and i went to o'riellys to get a new clamp. the only one they had in the shelf was a mr gasket brand clamp. it had a stud set up with it. so i tried to put it on but it didn't seem to fit right with my intake manifold. it was too bulky. i'm running an edlebrock rpm air gap. so i tried putting the stud on there with my original clamp.
