First of all Hello everyone.
I just bought a FL350 Oddy this weekend. This is the first time I have ever seen one. I thought it was very cool, and it was reasonable so I figured I would buy it and work on it, as I am a gear-head. I performed a leak-down test and it held 10 psi for 30 minutes. I did a compression test and it came back at 50 psi. Horrible. I pulled the head and it is clean. The piston has a little bit of carbon on it. With the piston still in the cyclinder I turned the crank and it spun very easy. I then pulled the cylinder and the piston and cylinder are unmarred. I cleaned the piston (sticky film on everything). I measured the bore quickly with an inside-bore micrometer and came out to 3.157in (80.188mm If conversion is right) I am not really sure what direction to go from here.
Also the reads on the intake are a clear plastic and one side had a gap between it and the housing.
thank you in advance for any help.
