Those are indeed the Fuel Jets off the short-lived 2-stroke piston-port Duramax.

They spray the fuel into the crankcase, where it mixes with air, then travels up the transfer ports to the chamber.

I was going to run one of those engines until I got a quote for getting 8 custom expansion chambers for it. :(

I was going to put it in a Quadracer, until I found out that Wade had already drawn up blueprints for it and had a patent on it.

IIRC, Wade sold a member here a block without the crankholders because they are optional on a Duramax, and just make rebuilding the engine that much harder.

X2, oil pan holds crank in just fine on my motor. I can also spin the crank faster with no holders. You guys are missing out by using these dumb holders for your crank.
