Good day everyone. I came across an old Honda outboard, eight horsepower, and the power head was salt encrusted so much that water would not circulate. The specs on it were a BF8AHLA, frame id# BACL 1000542. Model year 1987.
I removed the power head, and replaced it with a 10 horsepower head.
The 8 horsepower head had a CDI ignition system, the 10 horsepower head has a points ignition system.
I researched all the parts from one to the other, bought new parts for any differences I found except the flywheel.
I notice that all used flywheels for sale claimed to be for the 7.5, for the 8, and for the 10 horsepower motors. Even though the part numbers from honda were different they all look the same.
I installed a brand new coil, points and condenser, wired the motor exactly are shown in the Manual, timed it according to the Manual, confirmed delivery of fuel to the cylinders, and the damn thing won't start.
I built a small manifold to hold the spark plugs outside of the engine, and got spark. I rechecked the timing. Reinstalled the plugs.
It still does not start. I began to search for advice from Honda dealers, shade tree mechanics, used parts sales companies, and no one was able to confirm or deny any issue that I might have had with the flywheel or anything else.
Any ideas? Thanks in advance.
