Three Bond 1194 is available at Northwood Saw, a site sponsor. Good stuff. I've used it on several with good results.

Available at your stihl dealer.

Exactly and can be had from any decent auto parts. If they dont carry the motoseal they can have it the next day useally.

how necessary is it?

I'm getting ready to install a new p&c on a Husky L77. I've got the new base gasket, they don't apply sealer at the factory, right? So it's an option?

With a new base gasket I won't use sealant. If it's used i'll put on a thin coat.

For me its either or. A gasket, or no gasket and sealant.

Agree. Used Motoseal to seal my S25DA fuel tank , I split. Has sat for three days with fuel in it and still good as gold. Also use Dirko HT, but it is pricey.

Yes, use the motoseal, I learned the hard way regular RTV like Ultra blue, gray, whatever,
WILL leak after some time if used in a gasoline area.

I also have had great results using CRC K&W copper coat, especially for head gaskets, it is gasoline proof and great adhesion. The 4 oz. can is easy to use, includes a dauber.
