Briggs and Stratton 422707, sitting on a riding mower.
Ran and drove just stinking fine a week ago. Got it in today and when started - surged and hard to find a choke position that didn't have the engine surging - real bad at idle, just a tiny bit a full. When I did finally find a sweet spot, as I drove it, it kept acting like it wanted to die.
I adjusted the screw at the bottom center of the carb. Couldn't really tell that it had any affect whatsoever on the surging. I adusted the small screw on the left side of the carb - the stop/set screw for the governor linkage. If I adjust that two far one way - at slow speed, it idles in real big loops - at full throttle - small surges. If I adjust this screw too far the other way - the engine takes off sounding like it wants to make it to full throttle, and then it slowly comes down in RPMs - but RPMs remain high.
What should I be looking at. I checked the the throttle and choke cables just to make sure neither had slipped in place, they hadn't.
Few months ago I put new fuel line, fuel filter, and cleaned out the tank. Even took the carb off and cleaned it. As I stated, it was running and driving just fine and dandy one week ago.
