So you've gotten tired of the phillips head screws and decide to swap. You pack one to the hardware to play the match game. The selection is a little thin, they are either too short or too long but hey longer is better right? And the little bride has always assured you size doesn't matter so go BIG.
Well there is a gottcha on the 38's so before you go cranking them puppies home with the allen wrenchs LOOK. 3 of them don't matter screw away BUT when you get to the 4th, the one under the choke manifold you better have your eyecrometer working. When that screw hits the manifold it will peel those threads out of the throttle body in short order. And it happens I have repaired two sets of carbs (e-bay purchases) this has happened to. One pair with both holes stripped. The picture should let you see what ima sayin.
