Don't give it any fuel. Just crank the engine with the timing light hooked to #1. See if you're close on the balancer for base timing. Generally I do as SB suggested. I run locked timing, So I get #1 on the compression stroke, and line the mark up at 30* on the balancer, and make sure the rotor is pointed as close as possible with the #1 terminal. Usually fires and requires minor tweaking to get timing right. If it backfires thru the intake, generally timing too far advances, backfiring out the exhaust, too retarded, of course assuming the mechanicals of it are right (valve adjustment, cam timing, etc).

might want to leave the beer alone while you are working on the engine.espically this one.

Budman, I don't think you've got any major mechanical issues. Unless you're going to do a proper run in and heat cycle on your test stand, then you should just take it straight to the dyno. Backfiring through the carb is almost always not enough timing, or really lean. Turn your distributor about 1/4" counter clockwise, and wind your idle mixture screws out 2 full turns to start. Once it fires up, bring your rpm up to around 1800-2200 rpm and advance the timing to 30-35 degrees while you do your brake in run.

Is this a new balancer ?? I've seen the painted or taped on ones be off a few degrees straight out of the box, just a thought

Looks like I just needed to dial in some more timing advance. Fired up and ran fine on the stand. Thanks all!

Bud, my Dad always told me they call it dope for a reason. Good luck with your trip to the dyno. Please leave any smoking devices at home. And if you don't adhere to my advice for Gods sake don't share with the guy operating the dyno...

Excellent! How about some vids for us??

When is the dyno session?
