Hi all,
Looking for some help on a starting issue for my sons 2000 Polaris TrailBlazer 250. Most of the time it’s very hard to start and many times it just will not start. Occasionally it will just pop right off on cold start but not too often. Once it does start it runs perfectly. The carb has been cleaned multiple times and I also installed a new carb kit. The plug is new and has nice blue spark. The compression was under 100 psi so put a new Wiseco piston and ring kit in it with all new gaskets. Had the cylinder honed and the head resurfaced by the local machine shop. It was never bored out and the cylinder and head looked about perfect prior to the honing. This original piston and rings also looked good but since it was apart I still replaced everything with the Wiseco kit. Compression is now 115 psi. It seemed to be running good for a day or so but now it will not start again. Prior to the new top end, the plug would be wet when trying to start it. Now the plug is dry after cranking it over several times trying to start it. I have cleaned the carb twice since the new top end but it still does not seem like it’s getting gas to the cylinder since the plug is not wet. Spark is still good. It started twice yesterday and ran great but as soon as I shut it off it would not start again. Any help and ideas would be appreciated. If anybody in local in the Twin Cities (MN) let me know. Thanks in advance!
