Hey William, By rebuilt, do you mean the carburetor?? ..or the engine??.. if you rebuilt the carb and you did not remove these screws ( and count the revolutions out from lightly seated), then you did not do the rebuild the carb correctly.. sorry.. What, exactly did you do to the carburetor?? Please reply on here to me..with details!! thanks..
I cannot understand why someone that claims to have "rebuilt" a carburetor actually missed the BASCIS of carb rebuilding 090.. the air screw (the one on the angle toward the back of the carb has/is connected to the pilot jet system and the idle system, the passages that use this system must be perfectly clean for the engine to run properly.... the air screw has a spring. a spring seat and a o-ring for sealing on it.. the screw setting starts at 1 & 1/2 turns out from lightly seated.. then set the screw in the very side of the carburetor (its the one that controls the idle speed).. once you get the machine warmed up and cleaned out.. let it idle, turn the air screw in and out SLOWLY about a 1/4 turn at a time..EACH TIME ..waiting until the idle settles and then until you reach the point the machine idles as high as possible, then turn in it 1/8 of a turn.. then set the idle speed with the "side screw" to a speed you like... good luck...thanks!!
Warm the engine up then turn the idle speed down as low as possible to see if it will go into gear. If turning the idle down seems to work, turn the idle back up just enough to support running when the engine is warm. If your engine will not idle well then it may need carb work or other engine work such as a tune up.
follow ur throttle cable down to cars there should be a plastic screw close to cable to adjust idea but with polaris that screw can be hard to find with all the plasticc they put in way but if u can see carbs easy enough u will see the idle screw
probably you have some worn parts in the carb.a rebuild kit would likely help.befofore you do that,you might try adjusting the air screw on the carb and check for air leaks where the carb connects to the cylinder head.
