Not really tractor related... but I have an older Briggs & Stratton (probably 25 to 30 years old) horizontal shaft, gear drive engine off on an old retired walk-behind snow thrower. The engine still runs like a champ under load and really hasn't seen that many hours of operation considering it's age. When the engine is not under load, it will not run at a constant speed... it revs up, then the governor throttles it down, then revs back up and the cycle repeats. It repeats this cycle every second or two.
It really wasn't that big of a deal on the snow thrower as the amount of time the engine was just idling was minimal. I'm wanting to use this engine with a two stage hydraulic pump to power a log splitter. Listening to the engine bounce off the governor for any extended period of time is quite maddening.
Can anyone familiar with these old gas engines offer any suggestions as to what is causing it run irratically and what I can do to fix it?
