I have resently picked up a Honda BF30A 4 Stroke. The owner told me that it hasn't been running in about a year. I took the 3 carbs off and cleaned them. #3 carb was full of sludge. I got the engine to start but it's not running good. It runs on 1/2 choke and 1/2 throttle. I have checked spark on all wires and plugs (good). While running, I can pull wires 2 and 3 and nothing sounds or runs different, if I pull wire 1, the engine will stall. This tells me that the motor is running on 1 cylinder. Any suggestions. The motor is a 2002 and is obvious that it has never been apart. I looks like it just came off the show room floor. Please let me know if anyone can help.
