On morning my FS56 RC weed eater started fine, but would bog down when attempting to throttle up, was fine the evening before. So I assumed that the high speed jet was clogged or maybe the spark arrestor. Dismantled the carburetor, inspected, removed the high speed jet, ran carb cleaner through the hole, checked the fuel screen, didn’t really see anything, spark arrestor had carbon, but wasn’t clogged - cleaned it anyway.
Put it back together, seemed to run normally most of the time, but it would occasionally bog down, had to fiddle with the throttle to keep it running. Took it apart again, decided to get a carburetor kit, maybe the diaphragm was dried up or I had damaged it. Turns out a new carburetor cost about RGS same, so went that way.
Left the machine sitting in the shop with a carburetor removed for a couple days until the new one arrived, installed it & put everything together.
Went to crank it, wouldn’t turn over - stuck. Took the rear cover / recoil starter assembly off & tried to turn the end of the crank manually - nothing. Tried a pair of channel locks, barely moved it. Removed the plug, still stiff. Removed the muffler & looked in the cylinder, didn’t see much, put some Kroil on the exposed piston, it got easier to turn. After a couple of minutes it turned over easily. Put it back together, I started and now runs normally. What the heck caused it to lock up? I always use the Stihl oil, one bottle/gallon. And how does one adjust the high speed jet?
