Honda BF 2 stalling issues

Took the dink out for my first time with the Honda BF 2. A 2005 model Took about 15 pulls to start, I figured its the lack of manual priming. [Pls tell me if I am wrong]. However the trip got worse. The motor stalled approx every 4-5 minutes. Started again with about 5-6 pulls, but ran for the aforementioned 4-5 minutes and just died. Throttle speed was varied when it died. First time full throttle other times different speeds as I tried to find a rhyme or reason. It has only no ethanol fuel, however fuel could be 4 months old.
Any thoughts to assist me in my fix.
thanks
Paul

I dont know the exact issue.

For outboards, I use a trash can with water when servicing

I would replace the fuel and add the approximate volume of fuel system cleaner ex SeaFoam or equivalent, remove spark plug and re gap or replace it and inspect it for color and condition
I would check the plug is sparking too
if an inline fuel filter is present either clean it or replace. I am thinking it is a fuel issue and check the carb linkage is smooth and no leaks from gaskets, Sometimes the fuel bowl can removed and cleaned and examined for debris or dirt
If it has idle or high jets, the screws can be adjusted when running,'
Sometimes opening the screws to full open with remove blockage when running.

Sometimes running it in water tank for a hour a various speeds with fresh gas and cleaner will help
I dont have a manual for this OB to trouble shoot further

Assuming the vent is open and you have good gas, I would pull the carburetor off and clean out the jets. The carbs on these small motors are pretty simple and easy to clean

I had a similar problem on the water last year with a mercury 4hp. I watched a video on youtube and cleaned out the jets with wd40( I realize it's not carb cleaner). The engine has run fine ever since.

There it is... my inexperience, did not open fuel vent on the internal tank.
Thanks so much, glad it was a simple. Will try the trash can test. It'll keep me from the long row home. Embarassed

The beauty of the Honda 2hp is that it is air cooled therefore you can run it "dry" without any issues. I regularly run mine in the barn hanging off a bracket.

Was always curious about running it out of water as it does have a water pump that apparently cools the lower unit. Any chance of damage there?

I don't think that it has a lower unit water pump, since the heat generated by the lower unit is friction through the gearing and bearing. If that's significant enough to require active cooling, that motor is wasting a lot of power and needs to be redesigned. And Honda builds good engines. Honda does advertise shallow water running, as a further thought.

Unless you're counting the propeller as a pump, which it is.

Another random thought: could you have noticed the exhaust, which is under water?

They have an impellar in the lower unit. They say it is to cool the exhaust. I would think running one out of water for any significant length of time would at least melt or damage the impellar. I have had to change impellars a couple of times over the years.

There is no impeller .Air cooled motor with centrifugal clutch. Those plastic carbs are not real serviceable . They are easily replaced if you let fuel sit in them . Can run dry out of the water no problem .

Draining the float bowl is the right way to store any carburettor , thanks Roger !
