pwk carb swap ?tips?

Perhaps this can help someone save half a day or so as I oftem modify stuff and it doesn't fit quite like I thought. Over the last few years I got a complete pwk 39, the generic sudco kind and another body which came with a bunch of jets and needles. I didn't get the carb to fit into the rubber boot for the micuni round slide 38 so I modified the carb with gas tank repair epoxy to fit the rubber manifold for the 40mm one which I bought at quite high cost. Unfortunatly the rubber boot for the 40 is shorter and the carb didn't reach to the airbox rubber boot to my liking. Upon forcing into the 38 mm rubber boot for the reed cage I changed my mind that it isn't that bad. So if you wish to go from a 40 mm (we are talking mono shock backbone frame here) to a pwk 38 or 39 you will want to get the rubber boots for the 38 on each end. I am not going to really comment on the results of riding it but it sure seemed to go farther when I forgot to turn the gas on. Less weight too.
