Frank-
That one looks a lot like mine except for the super-long throttle shaft and the hose fitting on the distributor advance port. If there's a lot of wiggle room on that end, the bushings probably need replacing. After looking at mine, I'm thinking the bushings could be made a wee bit shorter, so they don't have to be contoured to the bore interior- that would make life MUCH easier. The throttle shaft on mine was worn eccentric on the linkage end, so I'll have to turn it down and fit an undersize bushing. If you have play- check this area also. I think a single Fish should flow enough to run your 260, but the intake manifold and heads also figure into flow resistance- multiple carbs will usually show less if the mount is a straight shot into the head. I'll see if I can get a friend to scan some of the Fish literature so I can email it- what's your URL?
