Farmall Regular carb or timing ?

440 sixpack · Oct 10, 2011

I have a 1930 Regular that we are having some issues with. When we belt it to another tractor it will pop off and we can get it to idle pretty good, when we try to rev up the engine it will spit and sputter and fall on its face. We have had the magneto off and rebuilt recently and I have put a new brass float and a new main tube in the carb. I set the float height so it is level with the line in the bowl. My question is if my timing is retarded too far could it cause this or should I be concentrating on the carb yet? If my float height is too high could this be the problem? When it idles it doesn"t smoke but it smells really gassy. I have tried adjusting the main screw on the carb but doesn"t seem to make a difference. Any ideas or comments are appreciated. Thanks

Not running rich? I.E. sooty plugs, rich exhaust?

If too lean, maybe a cleaning of the jet is timely. Mine just plugged yesterday on a new carb after rebuild.

Vacuum gauge to time it/ idle mixture. Set for the highest vacuum.

440, Yes timing to far retard you will have no power at top end. With #1 plug out and spark off to all put a long piece of wire in plug hole to piston top. crank slow. You should hear the mag snap a TDC piston full up. I have heard guy speak of the sweet spot. You would not believe how easy they start and run when you get it right. oldiron29
