"I just bought a Clinton 7.5hp
"I just bought a Clinton 7.5hp outboard which I think is a 1975. The model # is k7503107D, serial # 992732, and type # 6052207R. I got it running but it runs really rough. Every 10-15 seconds it chugs making a sound like gears hitting. I took everything except the head unit apart and it looks alright. I am reluctant to open up the head unit without a manual. I am mixing with a 40-50:1 ratio. Can anybody tell me the spark plug # or more importantly have a manual for this motor. It would help tremendously. Thank you"
