The H25 through H35 cranks are the same, as long as they're all 1982 or prior. The later H35 has a larger magneto side bearing surface.
(Even though I am not a "real" small engine shop.) LOL.
Since the OP is probably going to ignore this post too, if anyone else needs one, I have one, scuffed up, 5/8 PTO, not drilled, but with puller pilot which works great to direct the drill bit for drilling and tapping. The metal is extremely soft, and you don't need a guide to drill it. Or at least I didn't. Journal is out of spec, but so is every other old ass Tec crank shaft.
Flywheel taper is a bit ugly, but that would be taken care of when the flywheel is lapped on during assembly. Or I could clean it up apparently and rip someone off on ebay for $60 by using bore hatch marks to describe a crankshaft, without providing any specifications to it.
I hear you can time these things by simply comparing the last guy's bolt indentations as well. (wink)
