I have a Farmall A that starts and idles really nice. But as soon as I put it under a load it sounds like it's missing, and sometimes it will pop out of the exhaust and fire can be seen coming out of the exhaust as well.
I've been reading that I might be running lean, but there is no adjustment on the TSX157 carb to test that easy. I also have the opportunity to talk with the son-in-law of the original owner who actually worked with this tractor. He says it might be running lean because he's not sure if one needs to run richer with unleaded fuel.
Or it could be running lean because I have a vacuum leak, but I did test that by spraying starter fluid at every joint and listening for a change while it was running... but there was no change.
Or maybe running lean is not the problem at all. Does anyone have any ideas?
