Hi all,
after letting my 52 model A sit for 6 years outside after it quit on me one day, I've decided to go about getting it running again.
The tractor has always had a problem "hunting" at idle. I could never get the idle screw to help level it out, so I figured the problem was in the circuit.
Pulled the carb off today, and drained out the varnished gas. The carb wasn't in too bad of shape, the bowl was full of rust which I buffed off with a grinder. The passages for the full load and idle circuit were clear as well as the vent. Should there be anything else that would effect the idle of the tractor?
The needle and seat look good as well. I rebuilt this carb about 15 years ago when I was just a kid.
My main question is, the big spring under the nut that holds the bowl on to the carb. What exactly is it's job? when I take off the nut all that comes out of that spot is the spring. am I missing some parts? what the heck is it there for?
While I'm thinking about it, I remember reading something once that a paper air filter element would make a good replacement for the oil bath? was off like a nissan pickup or something? Anyone remember?
Also thinking of converting this tractor over to electronic ignition since it has the delco distributor with points. I've done it to my 2520 and it's worked great.
