Well in 2012 I burnt the motor up the first time I took it to the lake. I found out why you don't trust the old auto blend systems. I knew nothing aboutYou have to lift the powerhead off.-----You have to split the block.----You have to lift the crankshaft about 1/2" to get reed blocks out.----What is your motor doing / not doing for you ????
Well its good to know its most likely not the reed valves. Yes he rebuilt the carbs and fuel pump replaced the stator and the fuel hose. Of course this was all done in 2012 so its been 11 years but it always been a problem. I've always had to goose the throttle a little every time I put it in forward or reverse because it tends to die (which I have always attributed to the stainless prop being much heavier than the original aluminum prop) if I don't and just kind of idles rough. if I give it just a little throttle its fine. But if I set the idle at the rpm recommended it just seems a little rough and will die if i don't give it a little throttle. I have also replaced both switch boxes the starter and starter solenoid.Unlikely your issue is reed valves. Your carbs are all cleaned and rebuilt with new gaskets, inlet needles, seats and floats? Your ign timing is spot on? You are adjusting the carbs in the water, in gear with fresh 50::1 fuel mix?
Those things are necessary. A leaking fuel pump diaphragm can also cause the engine to bog upon acceleration.
Is it best just to keep all the carbs the same? Otherwise how do you know which carb is off?Open low speed mixture screws about 1/8th turn at a time.-----That usually makes the bogging go away.----Do this with boat floating in the water.
