Okay, here are the pics of the dizzy. It was running pretty nicely at idle with occasional popping. When I revved it it would backfire a bit more. When I snapped the throttle wide open it backfired through the carb for the first time. Finally got it running pretty well. Timing at 12 degrees BTDC. Pretty much quit backfiring at idle. Hooked up vacuum advance and idle ran way up. Still ran nice, good throttle response. Took it for a drive and absolutely no power. WOT and I got maybe 35 MPH. No backfiring though. I turned the next road and started home and it started backfiring loud and often. Put in neutral and backfiring stops. Coasted home. I have a couple videos of the backfiring as well. Kind of hard to hear, but it might help. http://www.youtube.com/user/branchingout3#p/a/u/0/FMbJ3auUgE8 http://www.youtube.com/user/branchingout3#p/u/0/p6u5ufKdinA
