Satoh S-650G Valves

[threeonefan]

I own a 1975 Satoh S-650G. Last fall one of the push rods fell off the rocker arm. It was simple enough to put back on but has fallen off a couple more times since. The engine hasn't run quite right since either. Do I need a simple valve adjustment or is this something more serious? Also I'm in need of a shop manual for this tractor. I have the parts book but seem to be having a bit of trouble finding a repair manual. Thanks for your input.

First you need to adjust the valves, if you hyaven't al ready done so. I have shop manuals & new & used parts for your tractor.
