[QUOTE="Pappy, post: 458147, member: 3278"] [size=5]Remember that you cannot just look at the opening at the rear of the carburetor....you have to look inside at the actural venturi size. There were no magical 15hp carbs, no matter the year, that would produce more propshaft horsepower. The changes I outlined were and are the basic changes needed to completely change a pre-92 over to a 15hp (depending on the year). The outside of the exhaust housing changes made no difference as did the thermostat change which was a super early change. Ignition system changes were only early changes as well. The 1974-75 engines had a pre-magflash ignition system that could be pretty frustrating at times. [/size] [/QUOTE]
