Hey guys I have a 99 xpress 300 and I'm having an issue, I rebuilt the engine and it will only start when I put my han over the intake on the car (when I manually choke it), I am not very familiar with plunger chokes.could some one help me understand how this choke is supposed to work and maybe how to ajust it so it works, thanks!

Howdy all, new to the forum, forums in general, and 2 strokes altogether. I have a new to me 97 Polaris Express 300, it has been bored .30 over, running 40.1 premix, oiler lines are blocked off. I admit my ignorance of 2 strokes and I'm Louznmemind with this thing.... I cannot get it to start without holding the throttle wide open and it will not idle on its own no matter what I do. Once I get it started I have to hold the throttle slightly open to keep it running, it will go into gear and SEEMS to run good all through the throttle range, it screams at WOT but when you let off it wants to bog out, it will keep running if you keep bumping the throttle. The carb has been taken apart and cleaned although it looked brand new inside when I took it apart. The main issue it had when I got it was it would pour gas out of the overflow as soon as you turned on the petcock, I replaced the petcock and adjusted the float height, I also replaced the float needle and seat but I'm not sure I have the float height correct. Is there a process to adjusting the float height considering it is made into the float bowl? Could this be my issue or should I also look elsewhere? I have tried adjusting the air screw to no avail, even at 1/8" intervals but the idle never changes at all, what is the default setting for this screw as well as the idle screw? I apologize if this is confusing or if I missed giving any necessary info but I will do my best to clear anything up if someone could please give me some advice.

New to me xpress i believe shuts down when put into reverse, but if i hold the override button it will remain running. This is not normal operation based on my scramblers i've owned before. She also grinds when i attempt to select high gear and wont engage. lastly she runs great in low gear . I dont know how to fix this or where to begin my troubleshooting. 1994 polaris 300 2x4 thanks in advance for any suggestions/solutions
