My A falls on its face

[Nimrod77]

My 52 A. Idles great. Revs up good. Put load on it. Starts to sput around and falls off fast to stalls. I’ve check valves. Adjust carb all over the place. Any other thoughts? I’m new to deeres Thanks.

Maybe try with the air cleaner unhooked.

Id check point gap and plugs, sounds like its dropping one cylinder under load

Could have weak spark. Does it have a magneto or distributor??

If it has a distributor run a jumper wire from the battery directly to the ignition coil and thereby eliminating the key switch and wiring. I've seen a G act up similar to what you describe and it ended up being a key switch

It has electric ignition. In distribtor. I just re wired a new switch. I’ll run a jumper wire and see if possible I have a week 12v wire

The carburetor has two adjusting needles, one idle and one for load. It is possible that the load circuit is somehow restricted which would cause stalling out under load. One way to check this is to screw in the load needle and see if it continues to act the same way. If it does, then the carb needs to be taken apart and cleaned.

That was it. My new line had dirt. New Tubing I didn’t blow out. My bad. But thank you all. Was actually easy fix. And loaded down on dyno and ran great.
