hi! I’m new here! I’m trying to help my father with his 1990 fourtrax 350. We got it new and has been very reliable. But now, if we don’t use it for 1 day, it will not start. The engine cranks, has spark but no fuel. If I remove the plug and pour some fuel in the engine, it will start right away and will be fine. I can shut it down, restart and drive all day without any problems. I don’t have access to it at the moment, but I’ll check it out when I go there next time. I hope you guys have some hints for this strange problem. thanks for your help!
