1986 Onan BFA 4 - Suddenly running rough
Well... as they say... "spark or fuel." I have my own suspicion, but I'd like to hear yours... She's been running great for the last 2 years / 25 to 30 hours since plugs, points, cap and rotor, oi...

We had a BFA that I bought used. I've cleaned lots of little carbs and couldn't get it to run right. Luckily there was a fuel system shop in town. Used to be a "carburetor shop" but now very few carbs, more and more fuel injection work, even turbos. Anyhow, they did a rebuild, with ultrasonic cleaning, and it ran right afterwards. They asked "Did you know there was GUM in some of the passages?" Yes, that's why I took it to YOU!
Oh, if it doesn't run "quite" steady, try replacing the Governor Spring. I think the parts list calls it "Music Spring." It's a ways down in the troubleshooting chart, but for about $3 I thought it was worth a shot, and it was.
