so I have a blaster was sitting for about 2 year, I just took it out cleaned the carburator and could not get it to started with the choke on but as soon as I put the choke in and gave it no gas it sort of idled, as soon as I try to give it gas in wants to die. I turned the screw on top of the carb all the way to the right and the smaller screw on the side of the carb out 2-1/2 turns insted of 1-1/2 and that seems to help stay on but again as soon as I give it gas it wants to quit some please help!
