I have a Honda BF 40 2004, purchased new, that began to demonstrate a loss of power on its first outing this year after a long Wisconsin winter. Before winter ,I always drain the carbs and fog the cylinders.No changes in prop etc
It starts and idles fine ,but has hardly the power to plane out my 16" boat.As suggested by many of you on this site more knowledgeable than I about these things, I replaced the fuel filter, installed new spark plugs, pumped Sea Foam into the system, and now most recently pulled the intake manifold and carburetors to do a more thorough cleaning. At the same time trying to do some fishing in between the trouble shooting.The carbs really didn't seem to be dirty, none of the goo Ive heard could be there. The #3 did have a small amount of the green powdery brass corrosion on the main and jet nozzle ,but it was just a small surface amount and didn't appear to occlude any ports or change the shape of the nozzles.
Pumping the fuel bulb has no effect.
Partially closing the choke does cause an increase in RPM and power. I'm stumped, there is really no reliable Honda mechanic within 200 mi
