Hello I have an old little craftsman snow blower with a 2hp engine I think it is Briggs but I'm not sure. But is has a probolem when I go to pull it it won't start won't start I can pull it forever it just won't start but when I put starting fluid in the carb after 3-4 pulls with starting fluid in the carb it will start and run for a few seconds then die. So I looked up a new carb and just couldn't find one I also looked up a kit and couldn't find that ether I got fresh gas in it and it gets good spark and by the way it is a 2 cycle I wound really apresheate any help
