I have a Farmall A that has been retrofitted with a distributor. It still has points. Anyway here are my issues:
The tractor was running a little rough, I have had issues with sticky valves and I got that freed up. The issue improved considerably, but the tractor still sounds like the RPM wavers a little and it just doesn't sound smooth like I think it should.
So...I attempted to adjust the carb. There is no power jet adjustment. Just Idle adjustment. No amount of idle screw adjustment makes any appreciable change in the way it idles. Screw it in all the way, runs OK, screw it out 5 turns...same. So, I rebuilt the carb. It was in pretty good shape anyway, but I cleaned it all out and got new seals in and a brand new idle needle. Still, the needle makes ZERO difference in the way it idles.
What is the deal with that??
Also, Timing adjustment. How do you do it? I have read a post here about turning the distributor 30 degrees CC and checking for spark, but no matter how many times I read the post, I cannot find a practical way of accomplishing this. I cannot locate any timing marks, so I am actually staring at Cyl 1 TDC through the spark plug hole. But how do you actually time it? Where is the procedure??
Any help on these issues is appreciated.
