Hi Jeff,
I built an F/C one for this bloke last week and starting that was not a problem. I am 100 % convinced the PT on these is a dud design, great motor, great base but for some reason the combination does not work. No idea why yours works so well.
MF,
Good idea but you can't fit the starter motor because the belt tension adjuster bolt pushes on a plate where the starter motor would be fitted. The other issue is these machines often only get used a couple of times a year to clear blocks so every time you went to use it the battery would be flat.
Apart from the pullet you need the adapter plate that bolts onto the motor and that then bolts to the 2 slots in the base so you can adjust it in and out.. I guess the ring with a piece of threaded rod welded to it that is used to adjust the belt tension is missing but that is not a big deal you can get around that easily.
