ORIGINAL: Antique

As with EVERY engine I buy, it will be completley dis assembled to check it out, then put back together and tested...With about 6 different size props..No relying on someone's optomistic numbers.....Not worried about any warranty...
The hub will be put back on the crank with some Loctite on the taper or straight shaft, whichever it has...The retaining nut will be as tight as it can get it with my 10 inch socket handle...The crank will be held from turning by a 10mm stopper in the spark plug hole, as sold by brand Z for their engines...Part # 4810-96220, Piston stopper...Brand Z torque for the stud is 80-120 kg.cm, whatever that is...With Loctite...
The engine will be bolted upright on a mill table..The hub will be lightly surfaced using a solid carbide 1/2 inch end mill, to ensure exact 90 degree to the crank sufrace...Not that I don't trust Todd, I'm sure it willl be perfect as delivered...I just do it to ALL my engines...Just in case..
