I have an 86 200x and got some problems. When the choke is open and i give her a kick it feels like there is no compression and wont start, when the choke is closed it will start right up with a little push on the throtle. It does'nt idle when its closed. but when you open it up after its started it idles fine. then if you rev it up it sounds like it wants to die until you let off the gas and it doesnt do that when the choke is closed. well i thought it was a dirty filter, so i took the air box off and it helped a little but the same problems are still there. I have no mod's on it and it never did this before. and all hapend after i was going to clean the carb but dident get to it so i just took it off then put it back on. changed the gas and oil couse i thought mabe there was water in the gas. is the jetting mest up or what?
