winter project

[Shedonyourlight]

Intentions were to do some work over the winter but things got in the way and the little CT 90 project got shoved into the corner. I bought it last fall for $600 and it ran a bit but seemed really weak. I tried to start it a couple weeks ago with no luck. Stuck a new battery on it, had good spark and was getting fuel. Checked the compression and dammit - 60psi. It needs 150 -175 to run.

So yesterday, I popped the head and jug. Dammit again. It looks like the jug had water in it at some time. There are a lot of pits and some scoring in the bore. The piston shows a lot of abuse as well. The head is carboned up but with a cleaning, it should be good. I'll probably lap the valves and throw in new valve guides while I'm in there.
