Thanks Bill, Brian, Thomas, Sleddog, Zee, Propforward, and Bob for your comments.
Sorry Rudy, I didn't take any photos along the way. I would like to add a governor at some point but I need to finish the fuel system.
Brian, thank you for all your posts. I learned a lot from them. I had to make a 2nd piston for this one. I failed in my first attempt. I lapped the fresh off the lathe piston and sleeve with brasso on the first one. It was leaky. I could see fuel bubbling out from the back of the piston when I flooded it while attempting to get it started. I then spent an hour and half lapping the cylinder with a commercial lap and 320 grit. I took about 2.5 mils off. Went from .505 to .510. It took that much to get a uniform gray finish in the bore. Then I snuck up on the piston od using the sleeve as a gauge. Once the piston would wiggle in an few tenths of an inch I then parted off the blank and finished the other features. I then used brasso and oil to lap the two together until silky-smooth full stroke. Took a maybe a couple hours. It is a very good fit with enough compression to hand start.
