Honda BF2D Float chamber drain ?

[jakeroyd]

Put my little 2hp Honda outboard on the gate to run it up today.
As a consequence of it being higher than usual I noticed there is a hole in the lower engine shroud which gives access to a screw.
Looks like it's screwed into the bottom of the float chamber on the carb. it's vertical with the head of the screw pointing down.
Tested it with my screwdriver , it's shut but only very lightly nipped up (maybe 5nM ?)

I assume it's a float chamber drain or possibly holds a jet in etc.

Can anybody expand on this please ?

Can't find any real refernce to it in any of the manuals i have and it is not I think something you service.

Motor runs fine by the way so there is no need to mess with it.
I always run the carb dry anyway after finishing using it

TIA

If you have the manual, page 62 under Storage shows "Drain Screw"

Can't be sure of which screw you are looking at, but there certainly is a float chamber drain round there somewhere. The instructions that came with our engine do tell you to use it to drain it down before long periods of storage. I never have since ours is in use the whole year round.

Thanks Stork 3.
You are correct that's the screw I am asking about and it is the float chamber drain.
i guess me running it dry each time achieves the same thing.

I have the manual but it's so long winded I don't think I will live long enough to get that far through it !

Start at the back then. You'll soon come to the section on storage!
