I cleaned the carburetors out with compressed air and carb cleaner got the boat running but bogging down and sputtering before plane. It broke loose finally and took off for 30 seconds or so when i had to slow down to take a turn. When i accelerated again it bogged down and died. Went home cleaned carbs again. Took two screws out that i hadnt before on the side of the bowl at the bottom. (One on each side). Inside were two much smaller screws that were deep in the housing that i took out with a really small screwdriver. They were completely closed. Are these my high speed orfaces? If so then how should they be adjusted? Also the orface (seat) that the pin goes into in the float chamber; is that my low speed orface? How should it be adjusted? It is also tightened. I feel like having these orfaces completely tight is restricting my gas flow to the point that I cant sit in idle without the cold start lever up. Sorry for long post....thanks in advance for the help!
