Looking for a little advice on the timing numbers I just pulled from my 73’ Duster (backfire issue)

Can both manifest themselves as a small plume of smoke that comes out of the carb right when I start the car? Sounds an awful lot like a *pop* noise…more so than when a car backfires. If you’re not right over the engine you wouldn’t even hear it or notice it.

That's a pop back through the intake and carburetor. Several causes. Incorrect firing order. Distributor out 180. Lean mixture. Incorrect timing. The problem is, all of those can also cause backfires, too! You just have to pay attention to "which end" it's coming from. lol
