Hi there, I have a 66 9.5 mq12, that has a broken motor mount I think. how hard is this to repair? also I took the motor off the boat and laid it down, now sometimes the float sticks and floods, I took the top off the carb and I had a real hard time getting the float to go down, had to do it 4 times. I just ordered a carb kit, comes with a new float, I hope that fixes it, anyone had this problem?
