motor has good compression, sparks good, carburator leaks, engine won't start.....where do I start to figure out the problem?

Lyle, sorry to hear of the problems. Seems like you should start with the carburator, and what do you mean the carburator leaks? Is it leaking into the cylinders or outward onto the engine. The latter is of course very dangerous and needs to be fixed but either way it seems the carburator is the place to start. By the way, what year is the engine?

hi there - since recent i own a '85 build 4 cylinder 2 stroke 50 hp mariner.

sounds like the same problem; if i prime the fuel one of the carbs starts pooring out the gas (eeek!). I think it just means there is goo in the carb's chamber and needs serious cleaning.

still wondering what fluids you can use to clean. I've heard it often is the 2-stroke oil that clutters up and needs rinsing.

Any good aerosol spray cleaner from a parts store will work. The key is to have compressed air to blow out all the jets and orifices before assembling the carburetor.
