I have Cliff's book and his rebuild kit.. I suppose I'm just second guessing myself, but he told me to open the idle bypass air to .090.. And I'm not really sure exactly which one is the idle bypass air on this model.. And he also informed me to open up the DCR's to .055.. Stupid question I'm sure, but what is he referring to when he say's DCR's.. Just don't want to drill anything without double checking.. Thanks again..
