mate i told you i was rough but. i recon you need the seal in the hole that the kill wires go into. may have something to do with vacume or pressure or what not. i took mine out and filled it with melted plastic. so i can only shut it off by turning fuel off, i dont recon a hole in a plastic carby is good, make sure the small plastic grommet type thing that goes on the center kill wire is in the carby all the way before you put the wire in then the boot then the other wire. simplze.
hope this is hepful
