False air/ leaking air from this area. How would you fix this? Liquid gasket?

My slides are brand new

Remove the cover and double check the installation of the diaphragm lip into the groove. It may have slipped during assembly. De-burr the grove and smooth the component surfaces as necessary. Re-install with a light coating of grease which will help hold the diaphragm in place and provide somewhat of a seal. Once back together, raise the slide, cover the vent slot with your finger and verify that the slide does not fall.

But you wouldnt use liquid gasket?

 

[hovel]

Not me. The "gasket" is the round edge of the diaphragm (like an 'O' ring) and if everything is clean and tidy nothing else is required. I like to use very light application of grease on all gasketed surfaces, just a personal preference.

I would be surprised if any major leak can happen there ..Surfaces are rather fine on carburetors
If the parts are not mixed or so --Cover shifted and / or wrong screw --- the one in that corner appears longer
--- Not tighted down right step by step
Personally I slop on gasket chemicals ,, But only a little on carburetors in extreme cases
Not for many years.
As a beginner I once clogged a Stromberg Carburetor for a VOLVO ..With Permatex .

I had a leak there once. It was due to the outer O-ring edge of the diaphragm slipping out of place like "hovel" described above. I used a tiny spot of Red RTV, but if I had to do it again I'd use "Castrol Red Rubber Grease" - Its thick and sticky. The job does not require sealant, just something sticky to keep the diaphragm in place while tightening the screws.

I use Dow Corning "High Vacuum Grease". Very thick, sticky and it's what it's made for. Plays very well with rubber.

Yes, I use the red rubber grease as well.
