Good day. I am curious on 2 things...first being how do I know if the mix ratio is correct...and second...when my engine is tilted all the way up for period of time there's a bit of oil dripping out of the carb covers. Any reason why

You know the mix ratio is correct by confirming that the oil pump link rod is set correctly. According to what the service manual says.

When the motor is tilted up the inlets to the carburetors is facing downward. Any fuel oil mix that is in the carburetors can drip downward.
