"I have a 2006 BF90, less than 20 hours. In spring it started perfectly. Within 15 minutes of running it started to run rough and then died. I could restart it with choke and it would rev but struggle and cut out until I repeated. Eventually, it idled rough and I got where I was going. It ran better at higher RPM but still cut out a few times.
Since then, it starts fine and runs great above about 2500 rpm, but sounds like it's intermittantly missing a cylinder below that. I've run 10 gallons through it with some STP type carb cleaner and put new gas in, same thing. Next time I get to it, (it's 250 miles away) I'll pull plugs to see if it's just one cylinder.
Although I used fuel stabilizer last fall, is it possible this is some gunk in a low speed jet on one carb? How big a deal would it be to get it out if that is what the problem is. I'm on my way to get a shop manual.
When this thing ran last year it was quiet and smooth."
