They say the diameter of the threaded opening is 1in and the hex part of the flange is 1¼in. They say everything moves freely. It is missing cap on top where the fuel line fits. They are asking $150. Is that a fair price?

I received patterns for the upper and lower timer brackets in the mail today. Hopefully it doesn't take too long to get them to the foundry.
Also at some point today I'm going to spend some time trying to get the stuck piston out. Will be interesting figuring out how to get it out of a headless 2 cycle cylinder. Will post more on it later.

Jeremy, if the piston is anywhere but tdc, find a piece of pipe to fit the 4" bore, press the piston inward 1/2" or so. It will be much easier to remove then. Do not press the pisotn above tdc, the rings can expand and lock in the chamber, breaking the piston out is the only option then.

That is exactly what we are going to try. The piston is at the bottom of the cylinder. There is about an ⅛inch lip of cylinder before the skirt of the piston starts. If you look inside the exhaust port you can see the top maybe ½inch of the piston and inside of the cylinder.
Today all I did was put the cylinder/piston, and some loose parts in the parts washer to clean everything up. I then put plugs in all the holes and filled the cylinder with the parts washing fluid through the open intake port. Even though there is a very low chance of that helping any.

Parts washer solvent is not a very good penetrating oil. It wasn't designed for that purpose. I don't know how I'd know that.

I don't know either. But penetrating oil isnt very good penetrating oil. Very low chance of it actually seeping around that piston. I just wanted it to get wet.

I usually put them in the press with the pipe on the bottom side of the piston, start pressing. If it's not moving and you have a fair amount of pressure on it, start heating the cylinder, it will usually pop loose before it's too hot to hold your hand on it.

Patterns should be going to the foundry on friday. Was going to drop them off this past weekend but storm damage and other pressing issues prevented it from happening. Also prevented me from making any real attempt at getting the piston loose.

Today was very exciting. My uncle found the right size pieces to fit the bore. Then, with a very steady hand, began to tap on the fittings. The piston immediately began to move inward. After moving in about ⅜ of an inch I noticed that the bore was wet. The parts cleaner had soaked all the way around the piston. After that we got a piece of ready rod and tapped the piston out from the top. The piston looks good. The bore looks good. The rings were all stuck but a little tapping with the plastig handle of a screwdriver took care of that.
Here are some pictures.

Finally got the patterns to the foundry yesterday. Should have my brackets in a couple weeks.
