47-55.1 Eliminate draft tube options

[dsraven]

if you could source an original dizzy, with the shaft and gear still on it, you could do a comparison and ensure everything is right before setting it back down in the hole. that way you're not as apt to wipe the crank bearings from lack of oil when testing. the shop doing your magneto may also appreciate the old dizzy for dimension checking.
maybe somebody on the site has a dizzy laying around that could do a gear OD and count the number of teeth on the gear and also the direction the gear is cut, just as a quick comparison check.
