Well, you learn something new everyday. I guess I will look into getting a gasket set and the supplies needed for sealing the engine.

Is that silicone sealer something that hobby stores would have, or more home improvement stores? And also, what is the Team Assocaited Green Goo Grease? Is it something special, or are there other things that are similar? My LHS doesn't seem to carry much Team Associated stuff, so I am not sure they will have that.

As far as gaskets and o-rings go. In the manual for the OS engine I have, there is clearly an o-ring on the back plate and a gasket (or gaskets depending temperature) on the head. Are you saying that a gasket on the head isn't necessary?

And I checked the glow plug first thing, and it works fine. Glows a nice red/orange. I will look at the carb more, as it does seem kind of dirty in spots. Or possibly I didn't prime it enough ... I didn't know how much was too much and didn't want to flood the engine.

Also, about the priming. When I put my finger over the exhaust port and pulled the starter, no gas was being sucked through. Could this be due to the lack of gaskets/o-rings on the engine? Just trying to figure out what is causing my issue. The only way I could get it to prime was to pull the exhaust tube and blow into it, pressurizing the tank and forcing fuel into the carb. And that plug the exhaust trick not working made me think something was wrong.
