Going to revive this old post in hopes somebody is out there that can sanity check me.... I finally convinced myself to buy a timing set and hooked everything up hoping to confirm that I was close on the timing, and that my recent fiddling (though it didn’t help much with the smokeshow) was getting close....
But according to the readings I’m gettting I was waaaaaaay off but is it possible for this thing to even run retarded?
After the engine warmed up it was idling around “-12” and when revved to 2000 rpm it read “-15” ... so I thought, “crap, I’m too far advanced I’m lucky I didn’t spring a leak in the head gasket.”
So I retarded it slightly, rotating clockwise, top side rotated toward driver side, and it idled at “-15” and revved out to “-22” .... so I’m thinking now that I went the wrong way?!?! That it was actually set at -15 (15 degrees AFTER TDC) and I retarded it further to “-22” or 22 degrees after TDC. So now I’m looking at removing fuel lines to rotate it WAAAAY further advanced... but am I going to “-8.5” or “+8.5”????
Sanity check, intuitively it’s showing the timing retarded after TDC since it went more negative as I retarded it more, but that would mean on the last test it was 30 degrees retarded from where it’s supposed to be at 8.5 BTDC... am I nuts here? I don’t want to nuke this engine after all this work..... help please.
