Default Replacing Carb Diaphragms

Ok... some of you may have know this, but I didn't.
I have a set of carbs that need a rebuild. I thought the diaphragms could be salvaged, but it turned out they were too hard. As many of you know, there is a guy (Rob) on eBay that sells just the diaphragms (4 for around $70 or $80). I think I figured out a way to EASILY replace them. I made a pretty crappy video of it, but I think you can get the idea. You can keep your original slides and this should save you some serious $$ for future rebuilds. I may ask Rob if he would do a VMF discount if we place orders through him over e-mail.... or Maybe we (or I) could do a mass order.

Anyway, check out my shotty vid and let me know what you all think!

Cheers,

Jeff

P.S.... did someone say "Sticky"?????

I wish I'd known this a couple months ago. I replaced my diaphragms without taking the slides apart, it was quite stressful and very time consuming. I ended up using a thin stainless steel washer that I sanded and polished the sharp edges off of to coerce the new diaphragm into it's little slot. I only wish the replacement rubbers were laminated with fabric like the originals. I really don't think the new ones will last very long but time will tell and, I can replace them four times and still save $$ over buying new slide assemblies. Thats for the elightenment and video.

I don't see anything wrong with the video. This is a major break through...

Perhaps a semi-permanent thread lock rather than epoxy?

Epoxy may not be the best solution, maybe a dab of silicone would work... I'm not sure what glues would work best in a fuel-rich environment.

Thanks,

Jeff
