There's one down side to the use of the H/W carbs. If you're a tinkerer, your fun will be limited. There's the choke to hook up, then the fuel line and throttle linkage to fabricate. And, of course, an air cleaner to fit. But then you're done. It's just going to sit there and work. No leaks, no bog or hesitation to sort out. No periodic readjustment. You'll have to find some other part of the truck to be frustrated at. <grin>
