I took the end cap off my muffler and I got way more power that with it on but now it doesn't idle down when I release the throttle. Any tips? It had so little power before I thought something was wrong with it because I ran into a car that cut me off. 80 cc 2 stroke motor on bicycle
 
How would I fix this? Bc with the muffler cap on it was struggling to get going I took it off and it flies now but it also doesn't want to slow down when I release the throttle the engine just whines And keeps going for a bit.
Get it idling and spray the gasket surfaces with some water. If it stalls then you have found your leak. Have you retorqued the head bolts recently?
