please help...I finally got spark but still cant get this thing started. ive even tried pouring a little fuel in the spark plug hole and starting fluid but nothing but an occasional backfire. I thought maybe it could be my fuel pump or lines, (I had to replace the tank & currently using a 1 gallon aluminum tank) but I am using clear fuel lines & can see the fuel going through it, its not a steady flow but when I pull on the starter it flows more. thank you
