Pony motor starter ???

Yes ny mate has done it,Its just a 12 V motor,that is anchored to the fender with a V belt to the Pony flywheel.You pull the motor to tension the belt when the pony fires you just release the motor tension.
It seems to work very well on his D 4 7u
PM me your email address and I will take a photo of the set up if you want

OM, Are the motors pictured starting motors or generators? Thanks for the info. quinq

If I was you, I'd forget going the "Rube Goldberg" route and find the Cat made parts. They are around, it's just going to cost you a few bucks. I converted my D2/3J to electric pony start using the original cat parts, it's the only way to go. You can also go direct electric start. Old Magnet is the guy to talk to about that type of conversion.

The motors pictured in OM's post are probably "starter/generators" which were used on some smaller farm and lawn and garden machinery. In that application they would have been permanently belted onto the engine instead of with the belt clutch arrangement shown.

There's not a lot of diffence between a DC generator and a motor except that the generator needs a regulator to control voltage and current.

I have one of these rigs on a D2 I bought that is a regular starter with a tiny pulley on the shaft in place of the starter drive. Seems to work just fine even though the 1/2" wide belt is trapped in the nose piece of the starter around the pulley.

For what it's worth, my D42T arrived with a configuration similar what is shown on the pics posted above. The generator contraption ate battery charge; did not spin the starting engine flywheel fast enough; was a real headache and pain making sure the battery was charged when I needed it.

Plus unless you have a battery box or plan to "strap" down the battery somehow, starting away from the barn or pick-up where you are holding your starting battery could be another real pain. The generator is almost guaranteed to bugger up your finder for the mount location.

I got tired of the contraption and decided to try a pull rope start on the starting engine. That has been about three years ago. Since then two pulls on the rope and 95% of the time the starting engine is rolling along, (knock on wood), and the starting rope only becomes a problem if I forget to take it with me on the machine.

I admit it could have been "new owner" error then, but would not change it now. If the starting engine craps out-I will deal with that at the time.

Pony's are a pain, but once it's dialed in and started once a month or so, they're pretty reliable. Mine always starts on first or second pull.

The warm temps. of Hawaii helps too, I'm pretty sure.

Nothing like a brand new magneto too. Once I quit messing around with the sixyty eight year old one. Including rebuilding twice, all my problems went away. That was the best $500.00 I spent on mt D2.
