I've been trying to clean out the carburetor on my newly acquired '87 FA50 in the attempt to exceed 24 mph. I've taken the carb off about 4 or 5 times now, going a little further each time as I teach myself about it. The problem is I can't seem to get the thing to come apart. I take off the four screws holding the bottom float bowl to the top air chamber, but the thing won't come apart. Is it just stuck real hard? Do I need to pry it apart? Or am I missing some other fastener holding it together? I tried pretty hard to pull it apart to no avail.
I've also seen others on this site talking of FA50's going 30-35 mph. How? I know there's no kits. Mines in near perfect condition, muffler's not clogged, propper amount of oil in the case, new plug, and the carb seems clean from what I can see of it, but when I hit 24mph it tops out, and not with a smooth hum, it sort of sputters a bit and drops down 1 or 2 mph then picks back up. Not a terrible sputter, but it feels like it's being governed. Any suggestions?
