I have a 76 75hp stinger i have rebuilt the carbs, and it really runs good. If you ease into the throttle, but if i just put the hammer down it sputters and stutters, till i let out of it then ease into it again. It will run like a raped ape i get 35mph with a 19p prop and 31 with one heck of a whole shot every once in a while with a 17p prop. It idles perfect some times it will load up after trolling for ten to twenty min i have to take to top off and rev it up smokes for a second then all is well again. But i still have to ease into. I think i should be able put the hammer down and go what else can it be. I have 128 on all three cylinders. Did a decarb hoping that is what is, it did not help at all. Any input would be great.
