51813 is what I bought and used on my 044 without a base gasket. It only has a few minutes run time so far but no air leak. Its what my local powersports repair shop uses.Loctite 574 isn't available locally, but Permatex #51813 is. Is the Permatex product usable?
Base gasket.
I guess they're both the same product but different label. The one on the right is what I have. I used to tie some in the corner of a sandwich bag and pipe it like icing drawing on a cake. Now I just use a q-tip to smear a thin layer on the surface. The less you use the better or it will squeeze out and gum up the piston.
Permatex grey is good ,i have used the black also with no problems ,i think the guys like 518 because it will wash out of the case if splooges in
That's a good thing and a bad thing. You want to rinse it with fuel before it sets up and freezes the piston to the jug, but you also don't want the 518 to be dissolved in places it needs to remain when it hasn't set up yet.Here what 518 looks like when you get a bit on your piston.

Like @junkman said "it washes away"
A couple seconds of run time and you'd never know the stuff was ever on the piston
Whenever I've used 518 I almost always start up the saw once I have everything back together. I only run it for a couple minutes. The cylinder doesn't get much more then warm. I do it mostly out of curiosity but doing it also washes away any excess 518 that got squished into the saw and into the piston.That's a good thing and a bad thing. You want to rinse it with fuel before it sets up and freezes the piston to the jug, but you also don't want the 518 to be dissolved in places it needs to remain when it hasn't set up yet.
That was my first thought, too. I like the Yamabond, Hondabond or the Motoseal. Pretty much the same stuff with a different label.That's a good thing and a bad thing.
