Hi everyone, I have a 1996 Polaris 400 xplorer and need to know where exactly the oil pump is located and how to adjust it. I took my quad in to a dealer and they cleaned and adjusted the carbs as it would not run. I also told them to adjust the oil pump but now it will run for a couple of minutes and then fowl the plug. If you put a new plug in then it will run good again for a couple of minutes and then do the same thing? Any other ideals besides the oil pump being out of adjustment? Thanks everyone.
