Is there a way to remove the rubber from carb. diaphrams without damaging the rubber? I'm working on a guy's Yamaha venture, and the slides are plastic rather than metal, one is missing a piece of plastic at the top, and there is another one that has pin holes in rubber. So hoping to switch good rubber from broken slide and putting in place of the one with pin holes. Afraid I'll just tear rubber up, unless these are suppose to come apart? terrylee
 
Seems logical to me that because the rubber is bonded to the plastic, any solvent that will remove the rubber will at least soften the plastic of the slide. That might not be the end of the world if they are non-functioning right now.

I've seen acetone do funky things to polyethylene in a very short amount of time, and the chlorinated solvents like chloroform and dichloroethane WILL soften plexiglass to the point where you can bond two surfaces.

Do you have some pictures of the slides and diaphragm?

There is a fairly recent thread kicking around here where a member changed his diaphragms with aftermarket. Worth a look using the search...
 
Wow! If that stuff works that sounds amazing! I did barely try to take rubber apart from slide and they are plastic and 30 yrs. old, the plastic fell apart, so looks like 2 new or good used slides for this guy. The slides are plastic with a metal tube glued about 2 inches inside that holds the top plastic ring on top to the rubber diahpram, and then of course a plastic ring on the bottom of the rubber holding it to slide. A lot like ones from my 850, but plastic slide instead of metal and of course bigger. terrylee
 
Nessism you're right, I saw the thread. And will suggest that to owner since much cheaper than oem. terrylee
