tried to start up my revo yesterday after about two months of sitting on the shelf and it was like I had no compression at all. It was running fine last time it was out and I haven't had the engine apart since. Is my 3.3 toast or could it be something else?

try cleaning out your carb etc. sometimes the fuel/oil will gel up. although if you motor has no pinch maybe you let it sit at tdc or something?

I very well could have left it at TDC, how much does that affect a well broken in engine, and am I looking at a rebuild?

Nah, u shouldn't have to rebuild a fairly new well broken in engine. As far as how much leaving it at tdc could affect it. It might affect it a little, but it shouldn't leave it feeling like it has no compression. If it seems like it has no compression after sitting like that, u might have possibly bigger problems than just leaving it at tdc; it sounds like it may have possibly been ran too lean at some point or another for at least a short period of time....
