Just inherited my fathers old snow blower which he hadn't used in a couple of years. Flushed the gas, added new. started right up but the unit didnt drive forward. Like an idiot I tipped it on its side to examine the pressure disc and didnt notice the oil pouring out the carb for a few minutes. Wouldn't start after that. Pulled the old spark plug to check for oil in the cylinder. none came out when i pulled the cord. Put in new spark plug, drained old oil and refilled with 5w-30 and it fired right up but will only run on 3/4 choke and full throttle. TYried adjusting screw on bottom of carb but it just kept stalling out. Is this because the oil that ran through the carb? Any suggestions would be great. Also Does anyone have a diagram of the carb? It may be missing an air filter, Im obviously not too familiar with these thing or I never would have tipped it on its side.
Thanks matt
