I was playing around with the mixture and there was no response from the engine it has a limiter cap on lt and right next to it is another adjustment screw it was screwed in tight I backed it out a little and gas started leaking from it,the more I backed out the screw the more it leaked. I am confused on what adjustment screw this if for?
