First time for me too. There were reports the dynamic, powerful A-65
sounded sick but it made plenty of power. Vern said, "It's poppin' and
crackin'. And Travis said the engine noise was "unusual." And Alan
said,
"Sump'n not right about that." So we pulled the cowl and sure enough
a
gasket at the exhaust flange had blown, or "blowed" as they say here in
WNC.

We'll see how them "no-blo's" from Superior work.



No-Blows work great! I cannot fathom why anyone would use the old
copper/asbestos "Sure Blow" gaskets when No-Blows are available.
Likewise cork rocker cover gaskets when the silicone rubber ones work so
much better.

Thanks, Orval. Maybe you can answer this question for me: the A&P says
to install the two thin plate exhaust gaskets from Superior Air Parts (SA
part no. 632837, I think) on each head so that the half-round bead is out on
each side, one bead up and one down. But the guys at Sacramento Sky Ranch
say the two gaskets should be installed with the raised beads interlocking
and facing the exhaust stack flange. Which one is correct?

The trusty A&P is off with a group of boy scouts sailing in the Caribbean,
lucky guys. And get this --- somebody donated them the use of a Navajo to
get there.
