I would like to correct the misconception about supercharging two strokes. By raising the exhaust bachpressure along with the intake pressure they can be highly supercharged. Snow mobiles are commercially available with turbocharged engines. The Rolls Royce Crecy and the Napier Nomad were a supercharged two strokes. The engine pictured below developed around 800 hp with nitrous oxide injection.

Rats. I tried to order the 17/32-40 tap from EX model engines but they are out of stock. I sent them a message asking if they were getting more in. Did anyone actually get an order in? I know other Cox suppliers still list the tap but have no stock and don't intend to get any more.
 
You can make a insert using 3/4" NF and single point the 40 TPI most lathes this easy to do. You use Aluminum or Brass. Note if use Aluminum and Aluminum body the insert may not come out

Shopgeezer. I managed one. At least they acknowledged my purchase and payment.
Maybe we started a run on the bank ;-)
