I think I might have found the fly wheel that came with my truck. It looks like the same one spoonrc uses, except his is blue. They could be different, but it honestly looks identical to mine.

Here is the link: [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXESB3]DuraTrax Flywheel[/link]

And this is the information from the CV-R manual on the piston/sleeve and the head gasket(s).

With this engine, the piston will feel tight
at the top of its stroke when the engine is
cold. This is normal. The piston and
cylinder are designed to achieve a
perfect running clearance when they
reach their normal running temperatures.

That answers the "sticking" issue I was having before. Thanks for clearing that up for me guys

About Head Gasket
These engines are fitted with two head gaskets
of 0.1mm thick and 0.2mm thick. It is
suggested to adjust the total thickness
according to atmospheric temperature,
humidity and glowplug used.
At early stage of running-in, when a glowplug
tends to burn out early or when high
nitromethane content fuel is used, try to run
the engine as it is.
When low nitromethane content fuel is used,
try to run the engine removing a 0.1mm
gasket.

So the engine comes fitted with .3mm of gaskets, and mine currently has none on it. That seems like it would be an issue. Then again, I don't know a lot about this stuff yet
