Fascinating, thanks Kevin!
I wouldn’t use this in place of cylinder base gasket, But maybe it would work? Depending on how flat the surfaces are. However it may also just blow out.
I’d love to get a tube of 1184 and try that but it’s not sold in Australia. Sounds like it has much longer work time that motoseal.
I have a tube of 1184, but never used it for anything. Like I said, I've never done a base gasket delete.
What I
will tell you is that I was putting compressed air into a Husky 2100 oil tank and POP went the tank!
What I had stupidly managed to do was split the tank halves seam. I went down a LOOOOONG, deep rabbit hole in trying to re-bond those tank halves. Tried the Yamaha, Honda sealants. Didn't work....because without reinforcement like screws/clamps, the halves looked like they needed(and had originally) an epoxy bond of some kind.
I bought a commercial construction epoxy that was supposed to impervious to just about everything. I super cleaned the two bonding surfaces. Applied the epoxy and let set for three days clamped in mild temps. Saw ran with no leaks for six months and started leaking again. The weak link seems to be at the rear of the handle.....which on some models(seemingly random, Husky-wise), they had a factory screw for reinforcement.
Needless to say, that took the wind outa my sails on bonding gas/oil tank halves. After that I got paranoid and started picking up used tanks....lol. Most of which have at least two threaded holes buggered and "repaired" with JB Weld......so there was always work to do on the tanks before they could go back in service.
My educated guess is that Husky had probably a clinic like environ when they bonded those tank halves together and of course the magnesium was virgin too. I envision people with operating skivvies and masks.......
