I'm finally getting my 68 Charger out on the road. It runs awful at anything more than 1/3 throttle. It just bogs and runs like crap.

I'm looking for ideas on where to start.

It feels like it has too much fuel and is flooding out, but I pulled a plug after my last run and it looked perfect. If the car is standing still, the engine starts and revs really smooth.

When I installed my Mopar electronic ignition, I ended up at around 16 degrees initial timing, and 34 at high rpm. (That was about a year ago, I haven't gone back and checked this again yet).

Any suggestions on where to start looking? I can I tell if its a fuel issue vs. a timing advance or ignition issue?

Thanks!
