Re: help! running rich

does it have a choke? how many turns out are the idle mixture screws? I keep the screws on my demon between 1 and 1.5 turns out. I know for the q-junks its something more like 4 turns out. I got my demon 750/mech sec. elec choke used for 50 bucks! threw a rebuild kit at it and it runs awesome. did you rebuild yours? Hope this helps you
