so i recently installed a 49cc kit on my bike, it runs, with a bit of persuasion. however theres a couple things ive noticed that make me wonder:
1) if im rolling along and i disengage the clutch the motor idles nicely, just needs a slight rev every five seconds or so so it doesn't stall, but as soon as i stop the engine stops, even though the clutch is disengaged fully and im revving the ****e out of it
2) when accelerating from a stop/slowly rolling, the engine makes a loud whiny sound that goes away almost completely once i gain some speed
3) there is black oily goo coming from the head gasket area. upon closer inspection there is a small gap between where the cylinder head attaches to the rest of the engine, i can see right through the gap around the corners. i tried tightening the bolts but they are as tight as they can be and there is still a gap. still runs for some reason, despite the little gap.
4) i noticed when riding that once in a while there is a louder than usual popping sound and a momentary loss of power.
5) inconsistent operation, sometimes it runs great, sometimes lousy, what gives?
6) some fuel is leaking out of the carb on the primer/idle screw side, not a lot, but its there. doesn't look like is coming from the fuel line or where the carb attaches to the manifold.
any ideas?
