RE: two stroke .74 fox wont idle
I have the EZ carb which is the newest version for the .74's as of a few years ago. Prior to that time they used an MK carb which had two needles. You will note on FlitelineSolutions link above, they recommend a new redesigned head button to solve some of the running problems. A fellow in Canada is making these buttons to the FliteLines dimensions which are $20 including postage. His Email address is given on their Fox site. Flitelines also shows the dimensions for these buttons so if you have a lathe or connections, you probably could get one made or make one cheaper
