Be very careful about the positioning of the carb boot clamps on cylinder #1 (forward right when seated). If you position this clamp the way the remaining three are positioned with the screw head accessible between the carbs it will interfere with the throttle linkage. You have to rotate it down so the screw head is underneath the boot, oriented toward the "V" of the engine. I used a long screw driver and approached it from the rear underneath the carbs with the fuel tank out of the way in order to tighten it.

Not sure what you're trying to describe here, Jeff, but I agree that the carb boot clamp screw should not be positioned between the front and rear cylinders. Here's what mine looked like when I pulled my carbs:
Click on the pic and then the zoom button for a closer look. The screwhead is on the forward side of the boot.
