"Hi,
Newbie poster here. Have a BF15D short shaft manual start tiller. Only about 10-15 hours on it (bought it in the spring from a guy who wasn't using it for the past couple of years). Used as power for my tender. Ran fine until last weekend when it all of a sudden started running rough / sputtering (sounded like it was on 1 cylinder) and then died. Started right up again / ran for a couple of minutes and did the same thing.
Pulled the plugs and both were dry - 1 looked like it had a bit of wear on the ridged connector so I replaced it with the only new spare I had. Same thing. Fired right up and a minute or so after died. Played musical plugs (having only the one spare) to no avail.
Checked the usual. Fuel vent open. Fuel in the fuel filter etc. Thought maybe it was starved for air but all the air intake seemed clear (appears to recycle some exhaust to preheat air going into the carb?)
Back off the water I phoned every Honda service center within 100 miles and no one can even look at it for a couple of weeks (and precious few of those boating weeks left out here). Almost every dealer said the same thing - sounds like the carb has varnish on it from ethanol and needs to be cleaned. Told me the only way to do it properly was ultrasonic cleaning etc.
Didn't seem like the carb would make it sound like it was on 1 cylinder but what the heck do I know. Fed-exd in a new carb which I just installed tonight. SAME PROBLEM.
Recap.
Starts fine with choke on from cold. Runs great for 3 to 4 minutes (choke now off) then sputters and dies. Starts right up again and runs fine for a couple of minutes and then sputters / dies. Starts right up again and again for progressively less time until, while it will start right up, now sounds like it is on 1 cylinder. Spark to both plugs. Lots of fuel. New carb. Lots of flow from the p-hole. Cool water from the p-hole but it is warmer for the few seconds AFTER it stops. Pulling choke while at idle when warm will actually kill it. Dies after this short period of time without regard as to whether it is at idle or WOT.
What the heck.
I'm sure a bunch of you are smarter than me and would appreciate any suggestions / input as my kids are dying to get back out on the boat.
Thanks!"
