Engine does have reasonable compression for a new engine that has never yet fired. I hooked it up with a v-belt to my 1800 rpm electric motor with a 1:2 ratio so it was turning at 900 rpm+/- for about 10 minutes without the sparkplug in it, to loosen it up a bit. I then put the sparkplug back in and turned the engine over with my variable speed drill. I had coated everything with oil, and as I turned it over, I seen ripples in the oil racing away from the sparkplug. Closer investigation shows that I need to machine the counterbore that the sparkplug sets in about .020" deeper to get below a cooling fin groove. That will be my first chore in the morning---Pull the head and machine the sparkplug seat a tiny bit to get a good seal at the plug. I will borrow a gas tank from one of my other engines.

It's been a GREAT morning here. I got up and borrowed the gas tank off my Odds and Ends hit and miss engine, did a little machining on the cylinder head sparkplug seat, hooked up the battery, and AWAY WE WENT!! I have lots of clean up and finessing to do, but we have a runner!!!!--Brian
