Reply to "UPDATED - Backfire under Low RPM / Load (4th or 5th Gear)....."

Thanks, Rodney -

I really believe (and am hoping) that none of the things you are describing are where my problem lie. I just put this motor back together about 1000 miles ago, after a spun rod bearing.

All this stuff has about 5000 miles on it...

Rollmaster Timing Chain & Gearset

Pioneer Damper

Timing matches on my balancer and degreed flywheel.

Ignition is a Duraspark, with a electronic pickup.

I really don't want to do the compression / leakdown test.

At least for now, I'm sticking with the carb as the culprit!

Thanks for thinking about my issues, though!
