Subject: [FlyRotary] intake manifold
porting question
I am finally getting my intake welded, using the
stock manifold as a plate and new AL tubes. Is it acceptable to use
something like Marine-Tex to help smooth the ports? Should I worry if a
piece of it comes loose? I plan on a turbo'd 20B.

I'm not too wild about marine tex (havent had
good luck with it so I use other brands of epoxy putty, your mileage may vary)
but my test stand engine has inhaled lots of epoxy chunks from quickly
fabricated test manifolds and has suffered no ill effects. Surface
prep is important to how well the stuff adhears.
