Does anybody have an idea how to repair an 05 polaris predator? First of all it will not start unless its been ridden for like 20 minutes and is hot.. Putting my hand on the carb and hand chocking it used to work but now it still won't work.. The only way to get it started is to pull start it with another quad.. I read online that its a valve issue but what parts will it need and how do I replace them? Please help and thanks a lot!
