Hey guys,
Slight problem on my 04 500, It seems like it wont idle at all unless the engine is warm. And its very hard to start. Normally always have to use the pull start to spin the engine fast enough to get it running. (could be another problem with my starter)
Any who, it does it at all temperatures below 65 degrees and the colder it is the worse it gets. I have taken the Carb apart multiple times. cleaning every time. I have bought a carb rebuild kit and swapped out all the jets, adjustment screws and needles that the stupid thing has. Float valve and seat are brand new. Jet needle is brand new and the clip is in the proper position.
I had a Polaris tech mention something to me about maybe the idle jet is supposed to have emulsion holes in it? or its not supposed to he couldn't remember. and dummy me lost the old one before I had a chance to check.
I had the carb apart last night and I went to town on it cleaning everything with 90psi compressor and carb cleaner. I thought it may have been the choke circuit but i can stick the little red carb cleaner tube into the hole where the plunger sits and shoot it in and it jettisons out the pickup in the bowl just as fast as I'm spraying it in and the same with the idle circuit...
I can crank the idle speed up when its cold which works great until it warms up and the the idle goes to like 3k RPM's and you cant shift or do anything.... oh and my idle/air screw is adjusted to 2.75 turns out as per the manual.
PS. I adjusted the throttle cable and the choke cables to spec, with no change. I wonder if its possible the ECT is bad? but wouldn't that cause crappy idle even when warm?
