Seakaye12, This CD-12 is a replacement for my 7.5 HP Ted Williams (McCulloch) motor that I have not been able to get running…Marvel Shebler carb is the problem. Actually I was trying to dial in the carb on the CD-12 after kit installed and new power shaft seal, prop seal and shift seal replaced. I was having trouble keeping the motor running at low speed and noticed that the carb bowl was not completely full. I guessed that the backflow preventer in the fuel line or the quick connector was failing. I installed a new fuel line and found that the fuel in the bowl was full but I was still having an issue getting the low speed idle dialed in. When I shut the motor down is when I noticed the oil/fuel puking out. I am going to try to get to the lake to test out/dial in the motor this week when I have a chance to dial high speed at WOT, then adjust the low speed idle.
