What should end play be on the distributor shaft. Mine already has a fairly thick shim in there, but the play is still around 0.053"
Could this cause erractic ignition? It stumbled and backfire when trying to run

There is alot of play in the distribs, but they work fine.
Thanks.
With the gears cut at a angle, does mean it puls the shaft down when running?
I would assume so.
That amount of play is normal , if you have side to side play @ the breaker point cam because of a worn upper bushing and shaft that would change the dwell, The point gap when its running but i doubt that's your problem. I would test your condenser with a condenser tester or replace it with a new condenser. if you have access to a working distributor machine preferably with a condenser tester meter , there are a series of tests to evaluate the overall condition of the distributor. I test all condensers even new ones before i install them. I would not purchase new old stock condensers on line because they are 30& 40 & 50 years old and wont pass the leakage test 50% will fail. I perform distributor repair and testing & test them on a Sun 504 distributor machine. Check your accelerator pump shot on the carburetor if that doesn't work that would cause it to stumble & back fire, also check for vacuum leaks.

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Hey guys,
I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
