If the diaphram was split/cut /cracked...the slide would not rise and you would have like no power at all. with the motor off..pushing the slide up and releasing will always result in some noise as the air exits and re-enters the hole in the bottom of the slide..normal.Dragon_MD said:When My bike shuts off the carb squeaks liek a dog toy. also when I push up on the slide in the carb.
Is the diaphragm cracked???
