Hi, My 25 hp has a problem that occurs at about 70% of max rpm. The Engine sounds like it doesnt get enough fuel/misfires a bit. It starts great, it idels great and it also works fine to about this 70% of max rpm. What I have done so far is:
-cleaned the carb twice (ultra sound cleaner),
-changed the plugs
-changed the spark plug wires and coil
-replaced the fuel lines from the connector to the fuel pump and from fuel pump to carbs.
-I used a different fuel tank to exclude broken fuel lines from the tank to motor.
Anyone had anykind of similar problem? Could it be fuel or electrical problem? The only thing i havent changed on the fuel side is the pump. On the Electric side it could be some bad contact in some wiring or the Engine Control module, or something else. Thankful for any kind of help!
