FS120 Surpass III Question
I am having problems with my FS1200 Surpass III engine and could use your sage advice. The engine is well broken in and had been a real trooper until this season. I now cannot get it tuned to reach a reasonable, steady RPM. I am having to run it leaned to about 1 turn out from closed on the hi speed needle and it surges while running at all throttle settings. I also have notice fuel spraying out of the carb. I've replaced the glow plug with a new Type F and reset the low end to the factory 2.5 turns from closed with no improvement. I'm thinking I may have a carb regulator problem. Is there any other troubleshooting you recommend to identify the problem?
