I have a s1 rb25det and it was running very very rough... cutting out when given any gas at all and did not want to keep running. I just changed the plugs and it runs better but it still cuts out when I give it any gas at all. then it dies after I try giving it gas a few times. When I changed the plugs I did notice that one of them was covered in fuel... and also when I give it gas some fuel is spitting out of the exhaust... Can anyone help me please???
