Just a note about something I’ve run across on Bay, apparently they make a taper to one inch adapter for Tapered pressure washer/generator cranks for those of you looking to build a yard kart for your Lil Racer or Grandbabies and have varied small engine involvement or even in the business.
They also make the 7/8” to 1” sleeve adapter for engines that are 7/8” straight shaft gas engines.
Comet and Noram made some fine 1” bore clutches for 41 or 35 pitch drive chains.
Consignment Auctions are a great source for these kind of engines on pressure washers that are often there because the pump went south or they didn’t drain the water and it froze.
The last I recall a dozen years ago the pressure washers that showed up without hoses or a “broken recoil“ at the Consign Auction were going for less than $10. I’d stay away from the Chinese-unmarked or unbranded engine and stick with the Briggs, Tecumseh, Honda etc. and other non-3rd world makes.
We, many of us knew about the crank adapters some used to convert stub cranks on old Mac saw motors that extended the 5/8” crank allowing the use of a simple 4 cycle clutch for just goofing about.
But if you’re stuck with a motor that’s tapered, maybe now you can make something of it. My filtered search only brought up a couple, but know some research might find you something cheaper elsewhere.
This eBay search is lowest first, U S seller only. Both shown have best offer option.

Mark,
This is good info, I know for a while minibike guys were buying 8HP surplus engines that had tapered cranks and had to swap the crank to fit a clutch on for minibikes.

Re: Crank adapters for those useless tapered 4 strokes
Thank You,
That where they got the nick-name "Crank Yankers" :~)
Smallest 35 tooth count for 3/4" is 12, so a 1" PTO to keep the gearing down, you need the 1" clutch bore but the bore isn't straight thru, That way they were able to get 10 and 11 tooth sprockets on such a large clutch, I've seen them on eBay and they weren't the 41 pitch, although I'm sure those can be had too. Obviously these were outboard drives to get the smaller gearing usually necessary for the fun karts in an effort to keep them in the 26mph parameter. Smaller driven sprocket and shorter chain saves the company money.
