I'm sorry if this has already been asked I looked and couldn't find what I am looking for. I have a 2002 Prairie 650, the slide in the one carb is not moving and I have lost quite a bit of power. I see I can order the slide new and it comes with a diaphragm. I was wondering if anyone knew if I can purchase just the diaphragm. I see there are a lot to choose from and none of of them have part numbers with them. The new part is $130.00 and am hoping I can get away with a less expensive option. Thank you in advance for your help.
