Hi everyone! New to the forum, well we actually used the site a lot which has helped up solve 99% of our problems with our engine but anyways. I've been searching for hours with no luck with a problem(s) we've been having. Our 80cc engine has been working fine for the past month but just yesterday it stopped, it's like the engine will start and only stay started if you pedal, but it doesn't like "go" if you know what I mean, and if you stop pedaling it dies. We've checked everything! We took off the cylinder head and there wasn't any apparent problems so we put the cylinder head back on and tightened the nuts in the "X" pattern and now noises are coming from the spark plug, the funny noise it makes when you remove the spark plug and walk/push the bike, sounds kinda like "pooshk" but this sound is happening with the spark plug in
EDIT: The sound isn't as loud, actually sounds like air seeping from somewhere, and the bike is able to move forward a little when the clutch is not engaged.

Please help, my boyfriend uses the bike to get to and from work.
Thank you guys ^^
