Honda BF 2.3D

Many thanks Milgrip, you've answered my question. I did not my realize there was solder involved. I am determined to get this motor running right.

One more thing, once the tamper proof cap is off, be gentle when adjusting the mixture screw as the slotted head is designed to snap off if over tightened.
They just don't want us messing with their over lean fuel mixture.

Surely if the jet is set correctly ,and the engine runs bad the fault is somewhere else on the engine , usually carb but could be fuel, electronics etc.

I agree, it could be a number of things, so I'm going to service it as comprehensively as I can. New gaskets and jets included. The carb is already clean , but I'll do it again. I always had Seagulls in the past, and usually the problem in recent years was the change in fuel, or breakdown of electrical system. I think I'm this case, if it's not the jets, then it is most likely air leaks.

I had this problem with my 2.3 a couple of years ago, stripped & cleaned a couple of times, then managed to drop the carb and break the idle screw. Bought a new one, worked well but didn't fit the antitamper cap. Also had to adjust the throttle cable. Now working fine. I always use Premium petrol + Honda additive. I don't drain the carb and this spring it started 3rd pull.

I bet your heart missed a beat when you dropped it !

Finally got the engine to run ok, but it's a fine line between idling and cutting out. New gaskets and jets installed and another clean. Have yet to use it on the boat though. I've been quoted for a new carb, but undecided as yet. I think the main problem is with the fuel, so I will be looking at that closely. Interestingly, I,ve had problems with a motor mower, which was down to an iffy float valve. But in the manual, it says not to use a fuel containing ethanol. Whilst cleaning the tank, I filtered the fuel, and found at least 10% of it had separated. Not sure if it were the ethanol or water. However, thanks to you all for your input.

This season. I've started using Fuel Set (plenty of other alternatives out there) in anything small and petrol powered like the outboard or a suitcase generator where the fuel will sit for more than a couple of weeks. I also use Tesco momentum 98 octane E5....These small engines seem hate this new E10 fuel. As I write, my outboard has been sat with this fuel concoction in it for a few weeks already, so I'll be interested to see how it starts when the time comes.
