Hey how’s it going?
Maybe you can help me. I have an AV7 engine with a 74cc airsal kit on it. When I put everything together and then put the cylinder on, there’s this weird resistance when the piston hits bottom dead center. Is this normal or am I an idiot? Like, I have to really turn the damn thing to make the piston come back up. Any ideas of what the problem might be or how I can fix it?
