I bought a brand new HEI distributor and it has an adjustable vacuum canister that I have never touched since I bought it and installed it.
Right now I have my engine base timed at 6 degrees TDC @ 500 (factory specs), and I cannot shut the engine off after a drive without the engine dieseling after I cut it off.
There's no way I'm too far advanced at 6 degrees TDC.
I have recurved the distributor by replacing the factory medium springs with some aftermarket light springs but I have never adjusted the vacuum advance canister and I think that's what's causing my issue of being too far advanced and causing the dieseling..
