hey, so my blaster was running really lean, and when i took the flywheel cover off alot of gas came out, like it was full, and there was alot of gas under the piston, turns out that the needle seat in the carb needs to be replaced, so its in the shop right now. im just wondering how would the gas get out of the engine around the flywheel and just sit in there? is it cause of the valve seat too or maybe a leaking crank seal?
