Honda BF2.3D Outboard Engine Fault Finding - Won't Start / Bad Fuel + Water - How To Clean The Carb

In this video, we have a look at this air cooled Honda BF2.3D outboard engine and why it won't start.
It’s not a good idea to run these engine for a long time out of water as per manufacturer instructions but a short test run won’t hurt. This is down to the build up of exhaust gas temperatures over a prolonged time damaging internal parts which would normally be in water

Very helpful video for future reference. I only paid 100 quid for mine the guy advertised for parts, the only problem was spark plug socket loose. There is another problem now a little bit of oil leakage from somewhere. I think gaskets need replacing. Thank you for sharing.

Let me know how you get on with the oil leak.
Location and how you fixed it 👍

Nice! Copied what you did. Had the exact same problem. Runs fine now😊

[@MarineEngineServicing]

👍 Brilliant, thanks for watching and glad it helped you !

I had mine cleaned. Now I empty the carb each time and stabilize fuel but far from a reliable engine and only 6 months old. I'm ready to give up on Hondas, bloody unless.

Sounds like the idle jet is still blocked if it won’t idle

[@demolaishonwow]

Too bad we cant see anything you do as you always point too high with the camera

[@MarineEngineServicing]

Hard to tell till after when using the head mount, will try harder next time 😅

[@demolaishonwow]

Rereading my comment i came off a but entitled, what i mean was more like i have this same problem and would have loved to see in more detail how you checked for spark :)

[@MarineEngineServicing]

@@demolaishonwowno worries,
I've got a video on testing outboard ignition, link below.
I know it's not the same engine, but the idea is the same for testing.
