Never used a plastic float. I don’t know if they ride different or are set the same way. You can ballpark it by setting similar to the brass float then subtracting a hair from the tang to open slightly early.
>>The carb linkages do open the throttle part way when the lever is at "fast" I was under
>>the impression that this was normal, and the govenor would open the throttle more
>>when needed. Is that correct?
Yes, the linkage throttle movement is a gross movement so it’s probably fine. The governor is generally active at slowing down the motor (pushed internally by flyweights) or passivly being pulled back by throttle springs.
>>I did install a inline fuel filter, could that be causing problems? but, then again, the carb from the st824 works fine with it.....
Also, draining fuel out of the nut will double check that Remember, you just cleaned your carb and having problems which act like the carb is dirty. You might want to check things again because it looks like some area you cleaned or set right is now dirty or set incorrectly. It won’t need another dip but poking the passageways and verifying the float will probably cure it.
Every time you put the gas line back on you are pushing hard on an old line that can easily break off crud immediatly or loosen the wall which will fall off later. Chances are the line did not come off easily and you had to use pliers or wedge a screw drive behind the line to get it off. That puts a lot of stress on an old line.
