If the tractor runs OK once it’s started it’s not probably not a valve adjustment problem (it would run crappy otherwise). More likely it’s either carburetion or ignition problem. A couple tests you can run:

1 – Pull the air cleaner gooseneck off the carb inlet. With the choke open (rod pushed all the way in) and the throttle open ½, fire a 2 second or so shot of ether into the carb while the engine is cranking. If it fires right up, it’s a carburetion problem. If it does not start or if it spits out the carb or exhaust suspect the ignition.

2 – Pull off one plug wire, attach a fresh sparkplug to the end and lay the plug on the coil. Now crank the engine and watch the gap at the plug. You should see a juicy, blue spark every 2nd revolution. If you get a lazy yellow spark, intermittent spark or no spark at all your ignition system needs work.

BTW a properly tuned Super M is one of the best starting tractors every made. Mine can sit outside for months in sub-freezing temperatures, yet lights off every time after only 2 or 3 crankshaft revolutions.
