Banshee being pain in ass, wont start

[IROOST1]

I have only started my 01 banshee 4 or 5 times since i rebuilt it last september. It started first kick once i rebuilt it. Then it got cold out and i had to rejet. The last time i rode it around, it ran pretty good. But the last 3 times i tried to start it, nothin. Now its like 50 out so i went to try and start it. Nothing. If i spray some starting fluid, it will start but once the starting fluid is burned off, it dies. I installed a new coil. didnt help. I have had the carbs off 5 times this winter to rejet and dont feel like doing anything with the carbs again. I have spark, new plugs, gas is about 1.5 months old. New intakes, compression was last done at 10 degrees out and had 120psi in each.

 

I might go out and clean the carbs in a little while. But i just dont understand why its being such a pain in the ass. My jetting is 290 mains, tors removed, idle screws set, 30 pilot, stock air jets, middle clip. mods are bills pipes, k&n with outerwear, boost bottle, lid off, stock head, stock port.

 

Also, my choke doesnt like to stay pulled out, could i have an air leak at the plunger.

id say drian that gas and mix up some new shit. some of the oil has probably seperated from the gas and is sitting on the bottom of your tank therefore being the first to go into your carbs. . clean the carbs and try new gas and plugs.

i pulled the carbs apart and cleaned the shit out of them and triple checked everything. Found a air leak in the manifold. One of the bolts i must not have tightened all the way. Fired right up then. Could have been way worse if i didnt find that.
