Did you try some penetrating fluid or WD40 to free it? You might be taking the carb off and rebuilding it.

Yes I did try just that. Didn't free it up.


in the picture the choke is wide open that might not cause it to start try closin it and maybe pour a little gas in it i doubt its stuck proboly just bein a bitch

check the trottle cable ,diconnect it from the carb and see if the linkage moves then.
