My 85hp Johnnson 1980 4cyl staring to go slow when I was going fast, then after a few trips it din't want to go fast,if I put it in full trotle it shut off,I test for firing and two coils din't fire so I put all 4 new coils,but it still was doing the problem and this time it staring to back firing I check my stator points and they where good, Back to the water it was going so slow no power and I could heard tha only two pistons were working, and it was using more gas than before,so I said to my sel if coils were no good power packs where about to go,I tried the spark firing and two look strongers than the other two, thats when I realize it could be my power packs or my stator without knowing tha the stator din't have to do nothing wiht this problem,so I got the two power Packs new, and know the boat is flying,but when I put it in full thotle it starts coughing, so I did what you guys toll me I took my carburetors apart and I found a litle piece of rubber inside the nidle of the float,know I got to put everything back together and give it a test I will let you know how it runs this time.
