My AFR Graphs

Bear with my while I try to post my results.

This is a print screen shot of my LC-1 O2 sensor at idle.

Muzzy Pro Pipe, Dyna Ignition, FST Stage 3 840. This is an idle shot on the rear cylinder with a 195 main jet, stock needle (no spacers), I do not know how many turns out on the idle screw. I just wanted to get close to 13:1. Comments?

Why do you have such a large number difference in jets front to rear?

Graphs look fine to me, I might shoot for closer to 12 for idle though

Going off some references on this site I thought that was a good starting point. I took her down the street just a bit, basically to turn it around and drive it back in the garage, and it ran like POO POO. Fell on its face, pretty sure mains are too big. I tinker with it more tomorrow.

Why are you focused on the idle A/F? No need to drive to test your idle.

Can you record your full throttle and 1/2 throttle runs? That will better help you tune in the carbs.

I will post more results as I obtain them. The neighborhood I am in is not Muzzy Pro pipe friendly.
