I use a general technologies TA-100. I really like it. It’s pretty accurate. Sometimes you don’t even have to put it close to the wire. Working on a pb-2100 blower last week, the tach worked and was laying beside it.

I have a 97. It’s a good bike. Full time 4wd isn’t great. Engine is very high quality. Very smooth compared to my Honda recon 250.
I had to put an axle in mine, same as any other 4wd.
I also had to do some work in the power transfer box, there is a torque limiting spring in there. I welded the...
I do agree, they were very late to the game. I’m pretty sure this twin I had was made mid 2000’s.
I knew the old iron ones had coil problems, the 17 I had also ate more than one coil(second was aftermarket)
I also had a 17hp single tecumseh one time, it too was on an mtd, 42” variator machine. Engine had plenty of torque. It didn’t bog down nearly like a Briggs. It cut more like a big single Kawasaki.
It seems they had a lot of coil trouble maybe??
I have an mtd mower one time with a v-twin tecumseh on it. Engine was a beast. I think it was a 42 or 46” cut, the engine easily could have handled 54”.
I’ve seen other mowers with tecumseh v-twins on them. Several Stanley mowers(mtd made).
I recently saw the ridgid small compressor is belt driven. That seems like a plus in my book. I’d assume the pump is lower rpm than direct drive and should help isolate vibration somewhat.
I’d say it’s the best pancake (oil less)style. Not sure about the “quiet” designs.
I still prefer oil...
Well Yamaha bought Subaru’s small engine. It was for a patent is all I know.
Yamaha wanted to get in the zero turn game. I’ve seen a few, never in person.
I agree, when adjusting the valves, replace the pull rope.
It’s a long way in them to replace a valve, I’ve done it.
Inspect the timing belt while the cover is off.
I’d also do a few oil changes on it as the capacity is pretty low.
Probably needs a new air filter, they kinda get rotten.
Usually when a kohler twin blows a head gasket, you can hear it. Sounds like an exhaust leak. “Usually” gets a little quieter as the engine warms up.
I wouldn’t think you would have 220psi with blown head gaskets.
I think the oil ring may be sticky.
I think id try to do a soak and get some...
