I bought a used losi xxx-nt and it came with a sirio .12 engine. I noticed it leaks a little unburnt fuel out the back of the engine. One thing I can tell by looking at it is that it doesn't have a head gasket and with the off when I bring the piston to the top it looks like it hit the plug and moves it up. I have looked every where for a manual or pictures of the engine taken apart but I can't find anything. Would there be any reason that it doesn't have gasket?

Thanks

yeah, the reaosn is that someone probably took it out or forgot to put it on there
