Does the engine have compression? i hear a "hiss" in the muffler im assuming on the exhaust stroke

Has it fired any at all? in the past it has it used to be on a razzle

You say you have tried to start the engine upright as well as inverted? yes i mounted it right side up and the carb seemed higher than the tank so i inverted the engine, now it seems to blow or backfire through the carb i dont really get too much exhaust out of the muffler.

Do you have it primed with fuel? yes but the fuel doesn't seem to keep flowing into the carb

Is the glow plug wet? every now and again when it hydro locks it is.

i know its hard to "diagnose" and engine especially since its not in front of you but ireally appreciaqte you helping me out. this is my first 4 stroke.
Thanks-Raf
