Thanks for the detailed explanation. I'll probably use the engine as-is for now, but I'll keep in mind all the options to restore the governor. Making your own air vane sounds same or more challenging than a factory restoration to me. Who knows, maybe in the future I'll feel brave enough to take...

So this "air-vane governor" is something you attache outside the engine, near the fly-wheel? Sounds like you wouldn't need to open up the engine to do this mod. Does Briggs and Stratton actually make an air-vane governor for this engine, or is this more of an aftermarket hack? I'm trying to...

It took me a while to get the impeller wheel balanced to minimize the vibrations. It's still far from perfect, but at least the chipper would stay at the same place now, when the engine is running. I had to order new shredder blades, it turned out the old blades were made for lawnmowers and not...

A quick update for those of you who are still following this thread. I hooked up the tachometer and fired up the engine, revved it to the max (bolted) position, it reaches roughly ~ 3000 rpm, but the real issue is extreme excessive vibrations. The whole chipper is jumping and moving around...

Yeah, all the linkages and the spring that connects the governor lever to the throttle at the carburetor are all missing. That's much more than I'm willing to invest in right now, both money wise and time wise. Maybe in the future when somebody is throwing away their blown engine and I'm allowed...

Yes, I think you are absolutely correct, this is the 130212 3250-01 engine. Based on the diagram in the manual, unfortunately, the previous owner removed the governor rod completely, as where it should poke out, now is only a bolt. See the attached pictures of the relevant pages in the manual...

Alright, attached are pictures of the blower housing. I also included the model number of the chipper found at the bottom plate. Any advise is greatly appreciated.

Thanks for the fast reply. Now I know I should not be running higher than 4k rpm. Onto he next problem, how do I measure the rpm? I guess a newbie like me can't tell the rpm just by listening to the sound of the engine. I'm eyeing some cheap tachometers on Amazon (they sell for < $13). You wrap...

I recently got hold of a very hold and rusted chipper/shredder. It's a craftsman model# 247.797851, I believe from 1990. Previous owner said it hasn't been used for years, but it did run fine before that. I cleaned the carburetor, replaced the spark plug and lo and behold the engine fired up...
