When you tighten the clamp at the junction of the carb and the intake boot to the reed cage, be careful not to over-tighten the clamp.
There is enough leverage in the clamp to distort the round rubber boot if over-tightened. This can cause the carb to separate from the boot under a hard shock. (cased landings, etc.)
I witnessed this happening to a customer's bike three times during a hare scramble, and upon inspection of the fellow's bike, found this problem. (The jump was right in front of my son's pit stop. Every time the carb & boot came apart after this one big jump, the rider's dad would put it back on and tighten it harder, which made it come apart even easier.)
I tightened it correctly, and it stayed on for the rest of the race.
I always put the intake boot onto the carb first, so I can put a finger inside and stop right before the clamp is tight enough to distort. Then, I connect it to the reed cage.
Good wrenching to you!
