Got a Farmall A which will start right up and run good. it will idle nice and rev right up, but will not run nice and smooth wide open. It has a mag. on it and also you can move the mag and the engine runs the same. You can screw the jet in and out on the carb and it makes no difference. My ? is has anyone any ideas what is wrong with this thing. Thanks. ps I have not seen this tractor yet, I am just going by what the owner has told me. I am going to go look at it tonight or tomorrow night. I also have a good distributor to put on to see if the mag is the problem. Just hoping you guys can give me some ideas to check out.

I agree with the plugs and wires. Make sure the wires are copper core, not graphite. Lastly, also check the valves, make sure the lash is correct and they are not "sticky".

Check for the proper muffler size. I think that model should have a 2" inlet and 1-3/4" outlet. This is necessary for adequate back pressure. I have a Super H that had a 2" inlet and 2" outlet. It ran terrible under load. Installed the right muffler and it runs great.
