I have a 65373R 1973 65 hp. When you give it the full throttle it cuts in and out like one cylinder is cutting in and out. The coils were all cracked and fairly old so I replaced them all. The fuel pump has been replaced. Sometimes it does run good and then it runs as if it loses one cylinder. Sometimes if I back off a little on the throttle and then give it the gas it comes on strong for a couple seconds and then dies again. All the fuel is new the tanks are new the fuel lines are all new. Spark plugs are new as well. Compression after warming it up and at WOT is 130 130 128.
Just wondering if anyone has any ideas before I take it to the marina.
