Hey Guys, Just got my new to me Merc running fairly well, at least in the test can.
I replaced the impeller, rebuilt the carb and fuel pump. New fuel bulb and quick connects
for fuel line. I got it so it fires on one pull yea! Smokes a bit much maybe due to rich oil?
My service manual says fuel to oil, 12oz to 5 Gallons, or 2.4 oz /gallon. 50:1
50:1 is I believe is really 2.56oz/ gallon. My bottle of Merc oil says mix 3oz/ Gallon for 50:1
I mixed 3oz / Gallon at the because I just read the bottle. No problem remixing but do you
guys think that much more oil would make the motor smoke that much more? Oh, 119psi in
both cylinders. Maybe I just need to run it under a load, but lakes are all frozen here now.
Second question, There are two bleed hoses, very small diameter hoses that run from the
cylinder block to the reed block connecting to two very small brass barbed nipples at the base. They
seem fairly tight when placed over nipples but either get blown off or vibrated off very soon
after the motor is running. I cannot find out what these are for, it seams that the motor runs the same
if they are connected or not. Thank guys!
