I just aquired an Evinrude Feetwin 7.5. in the motor instructions call for 1/2 Pint oil for every gallon of gas. what is the fuel mix ratio for this motor? This motor looks to be in the 50's with a pressureized tank.
I have a Johnson Seahorse 10 not sure what year but it has a fuel knob connected to the carb and not sure how to use the knobs or how to start the motor. also not sure what ratio gas to use?? Motor has compression and spark... any suggestions?
