Subject: [FlyRotary] HS Port Barrel
Valve Modifications
I did an archive
search and couldn't find an answer to my question...in Bruce T's O.H. video
it looks like he places putty direactly into the housing vs. into the barrel
valve as Tracy mentions in his book. Is there a reason why we can't
eliminate the barrel all together and modify (putty) the end housings
directly (as the video seems to show)? Thanks for the
info.

Doug, when I elminated the barrel valve, I
simply removed it and used a combination of an epoxy "stick" (which when
mixed, gives you epoxy about the consistency of dough) to fill in most
of the end of the cavity and shaped it so as to have good airflow into the
port. I think mixed some JB WELD and covered the dough epoxy and used
Lacqure thinner to smooth the surface. It worked just fine for over
160 hours until I replaced the six port engine with a four
port.
Good advice. The only reason I modified the barrel valves was
because I didn't plan to open the engine. This plan didn't work out
because I ended up having to overhaul the engine anyway. Better to
streamline the sidehousing port and dump the barrel valve as Ed
did.
