My King Quad idles nice and runs great on the level and going down hill. However going up hill it cuts out completley. The engine doesn't die it just won't go. I have changed the spark plug and checked the air filter. the vacume line going to carb appears fine. If it the carburator, How can I tell what model I have? Also could it be the fuel pump. Looks to be a bear to get to. Any ideas out there?
