carb slide diaphram loose

[garyS-NJ]

one of my sliders wasn't fluttering and I took it out and found the diaphragm rotating with respect to the slider.. and I could see a gap somewhere between the inner and outer slider pieces (I compared to another slider assy). so I aligned the diaphragm and then then held the slider and tapped the inside of the slider metal part so as to hammer the pieces together and pinch the plastic washers to the slider.. it worked but somewhere I read of a fix to use RTV to secure things but the post didn't say how to use the RTV. are these parts press fit?? how do we make them godly.

I don't know about "godly" but I just pressed mine back together with hand pressure whe I discovered they had seperated. The slides are plastic, the rings are plastic and the diaphragm "spacer" is metal. At least that's how it is on my 83's carbs.

 

Been that way for a couple weeks now, running fine, no issues.

 

I suppose a thin film of silicone wouldn't hurt, I just don't see the need as they work fine as delivered if everything is "as per".

 

You can just pull them out of the bore by hand if you want. Nothing besides the diaphragm holds them in. once they're out, getting them back together is a simple matter of hand pressure to re-seat the rings.

 

If you do remove them, carefully wipe the slide and the bore with a lint free cloth. They need to be ultra clean before reassembly. The clearances are small and any dirt can jam the slide. Forcing them back in will score the slide and potentially cause running issues.

 

I have been known to give the bores and slides a little squirt of clean fuel before assembly of CV carbs. Not so much to lubricate, but to flush any contaminants away. It's not required, just a practice I got myself into somewhere along the way....

thanks great white. I'll just watch them to see if any more come apart. like that. and yes when I got the bike after sitting for a while, the sliders were sticky to stuck. I PB Blasted them out and polished the slides and bores with a plastic scouring pad (with PB blast) and wiped and lubed and assembled but they still were all a tad sticky (some more than another) and so I tried electrical contact cleaner and silicone lube and finally seafoam. seafoam got them nice.
