Wow, I am starting to think I may need to toss this thing. I just took the carburator completely apart, cleaned the ports with a tiny wire and blew all the holes out. I rearranged the fuel line in the tank, which does not have a filter and did not have one when I got the machine. I got it started and it ran for about 20 seconds this time but stopped again. Then it would start then quickly stop again and again. I have rechecked the screws and bolts, which appear tight. Well, I think the next step is bye bye. Thanks for your reply and information.
