So we have now completed... rewire, new battery, new plugs, hooked up lights, distributor kit, new exhaust. Tractor runs, runs pretty good however still seems to be little rough. Have adjusted dist. ever so slightly back and forth until runs best where set. Also when running at high rpms puts out blue smoke like a banchi..Could this be the "BAD" gas that we are burning. Also neighbor has ordered electonic ignition for this. any thoughts on this?? The only other thing after all this would be the carb needing cleaned after gas setting in her for a year or two. Again thanks for all the help here as Ive learned alot about this little tractor. Pretty simple really.
