Setting my engine timing at 28 degrees at 3500 rpms I get backfiring/ popping
can this be caused by fuel starvation? or is this because of another issue i'm using the mark on the fly wheel to set timing any tips on trouble shooting? |

Always verify mechanical integrity first.. This means a leak down and compression test are done first.
If the engine checks out with no mechanical issues then I'd say you more than likely have a funky injector and that causing a single cylinder to lean out. if it does this on acceleration, try both low and high speed ACCEL enrichment and see if it gets better. |
