Hi all,
I have a 80's Honda BF100 long shaft used on a 22' sailboat that has a stalling problem that has me stumped.
Here is the issue : The engine starts fine (cold with choke, warm without) and will idle fine for extended periods. It will also run at ~50% throttle with no issues. The problem is that when you give it close to WOT it will run great for maybe 10 seconds then bog down to idle for ~1-2 seconds before stalling. Once it has stalled this way it is very hard to get started again, choke or not. You have to leave it for a few hours / days and then it will start again fine. Rince and repeat...
Here is what I have done for now : When it stalls I checked if it was getting enough fuel and there was fuel in the carb bowl (pours out if you open the drain). I took the whole carb appart and cleaned it, put it back together and readjusted as per the manual's instructions. Checked if the fuel pump was giving good pressure and it shoots out fuel if you disconnect the line from the carburetor while the engine is running. This leads me to think it is not a fuel delivery problem... Can the carb be giving too much fuel at WOT and basically flood the engine ? That would explain why it is so hard to start after...
Any other ideas? This has me stumped!!! Thanks!
