Hello Everyone. I have a 95 Xplorer 4x4, 2 cycle, that I bought used and it ran great for about 5 years. Suddenly, it would not hold an idle. It starts great and runs great to this day. But, it won't start cold and hold an idle. However, if I start it and keep it on choke to warm up... then put a load on the engine (i.e. run it full out for about a 1/2 mile... flipping off the manual choke after the first 50 yards) it will begin to idle just fine and run for hours. I've had it to the polaris dealer twice (i.e. replaced the throttle assmbly and cable, tune up, etc.) and to an independent (found a tear in the carb. boot), but this has not fixed the problem. It will not idle from a cold start nor if I have run it for a while then shut it off for a few minutes. I've rebuilt the carborator and cleaned it numerous times to no avail. Any thoughts or advice would be greatly appreciated. FYI, the polaris dealer has said it has very good compression for its age and is mechanically very sound.
