Hey, put together my first 66cc kit and was breaking it in, about 2-3 hours on it and I noticed oil/gas leaking where the head and jug meet, but not apparently leaking from the head gasket as I can tell from both looking at it and ensuring the the head is torqued down, but i can look again to double check. It is almost as if there is a small hole in the jug, when it runs it occasionally makes a loud crack sound as if the muffler was not attached making me think that I am listening to the internal cumbustion via this hole? The bike runs ok at full speed but come to think of it, it has lost a little performance. I am still breaking it in with 16:1 so I am guessing that the is the reason for poor idling.
I have been rebuilding Vespa and lambretta engines for over 20 years so I know my way around 2 strokes but have never seen this before, maybe it's a Chinese thing, I dunno. Any ideas?
thanks
Sean
EDIT: apologize, don't know why the pics got all screwy like that.
