Hi what kind of gasket glue should I use for inner outer primary?

 

You can put it on dry. If you need just a lil' to hold it in place to start the outer primary bolts, black gasket maker smeared real thin in small areas works well.

 

I use a little grease to hold the O ring to the motor, for the outer I use James gasket with that orange crap on it, if it leaks then I pull it off and spear a little RTV made for gear oil, Permatex #81182

 

Shovel primaries I use Permatex Ultra Gray on the o-ring sealing surface and on the gasket it it's the cheap plain paper ones, better quality gaskets with the silicone bead install dry.
