All mods completed for a 3 to 2 circuit on my GEN 3 1150 Holley. First start up today. Started right up, set float levels, set idle mixture screws all just about 3/4 turn out from seat. Idle set to 1000 RPM. After all settings took for a test drive. Car is much cleaner now I can be in the garage, with car idling. Crisp clean response, pulls a lot harder. After run checked valve adjustment running a solid roller, I must say shaft mounted rockers from TD hold there adjustments much better. Only 1 exh valve was a little tight, my fault when I set lash last year. Will pull plugs to see outcome of tune tomorrow. I read here on this forum 3 emulsion jets verse 2, is better? Might try this mod. I also like to thank who took the time to respond and help in previous posts. Took it for about a 3 mile ride just enough to get it up to temp, and warmed up. If any further tips please advise, Specs are above in previous post. Thanks Dave.

Anyone have feed back on the 2 circuit Gen 3 1050 Sportsman 1050 dominator? Cheaper than the Regular Gen 3 with most of the good features.

The 2 circuit 950 is real close, needs idle feed lowered and emulsion and main bleeds tweaked. Probably not much different on the 1050.
