Backfiring..12A vs 13B
I have a question about backfiring. Seems like once all my 12a 7's got over 125k or so they started softly backfiring. It's not a compression or a timing issue. It's actually a carb issue. It happens when I just deccelerate in any gear. I believe it's cause by the carb not mixing correctly at idle. I don't get backfire on quick shifts or if I decelerate with some throttle.
I was just wondering if 13b's also backfire softly like 12a's or if the EFI has significantly improved mixing.

That's what I am thinking...13b's mix better than the carbs do. My 2nd rotor float runs a little rich. I think the majority of the pops are coming from the excess fuel burning down through the exhaust.
