Hey everyone. I don't use Rhino much and let it sit for the whole summer and fall. Wanted to have a small trip last week and it won't run. It starts but when I give it gas it dies. I changed the fuel filter, pulled the carb to try and take it apart to clean. When I tried to pull the bowl off the bottom, two of the screws came out and the other two stripped the phillips head. So I sprayed a carb cleaner in it, put it back together and it still doesn't run. Any clues?
