Hopefully this will prevent others from having the distress which I recently endured.
I applied Permatex Anaerobic Gasket Dressing to the gasket on my Monobloc float cover. There was a persistent drip which tightening the three screws could not stop, despite a new Amal cover gasket. I decided to apply anaerobic gasket dressing to the cover side of the gasket, leaving the body side dry. I tightened the three screws, more than snug, but not overly tight, waited overnight for the gasket dressing to cure. The drip stopped, but after I cranked up the Atlas, I found I needed to adjust the float level, and when I tried to remove the three cover screws, I found the screws to be "LocTited". Apparently, anaerobic material got squeezed into the threaded holes and locked the screws. Two screws came out with only minor "boogering" of the heads, but the third required me to drill out the head. I was able to pry off the cover, and get pliers on the stub of the screw remaining. That screw required a lot of torque to remove it, as if it had been set with red LocTite. I feared it might twist off before breaking loose.
If I ever use anaerobic gasket dressing again, I will take great care to ensure the material does not get squeezed into any screw holes. I do not think I applied too much dressing, as I only applied a smear, with no surplus. Sometimes, the old fashioned stand-bys like Form-A-Gasket or Indian Head sealer are superior to the modern Hi-Tech stuff!
I hope this helps.
