Thank you for the replies Dennis and Mark! I'm keeping on digging in to the issue.
One thing I can absolutely agree on is that the engine should never run
backwards!

Thank you for all of the great advice, Mark. I appreciate you taking the time
to type it out, and I will definitely act on it.
In regards to the "why would you hold in heat" question, my apologies, I was referring
to a refuel stop on a XC flight, where you were just stopping for gas,
etc.
Thanks again!
Brandon

Not to add to confusions, but as I recall, if you use the firewall shut off
and then try to pressurize the system with the primer while the valve is in
the "OFF" position, it will cause the valve to lock in the "OFF" position.
Attempting to move the shutoff lever to the "ON" position will damage the
valve.

Good to know, thank you Sir. Note, I don't touch the fire valve other than to
ensure it is full forward on the checklist, just asked how come. Great responses
(and ones that I should have thought of).
PS - My Yak bears a GC tail number. :)

Have you ever confirmed the fire shut off actually shuts the fuel off?
I have seen several shut off arms on the firewall misadjusted and would
not shut the fuel off. It's a good idea to check the operation once in
awhilejust for safety sake.

Thanks Dennis, I had planned on confirming at conditional. One of my 172's failed
this test years back. Had to remove the fuel shut off valve and have it serviced.
It lasted a few years and started weeping, so I stuck a used one in. I'll
have to say that getting to that little bugger and putting it in or out is
a nightmare, in a 172 at least.

Big warning in Nanchang manuals about propping off with high CHT above about 80
or so. Also heard a story of a Yak guy losing a kneecap in Barwon heads Australia
moving prop after refuel etc. everyone thought he had left mags on .. but
I suspect the high cht / glow plug idea proposed earlier. As for closing firewall
shutoff .. also noted in manuals that it can cause back fire etc so not recommended
. If you want to test it disconnect fuel line after closing it and
see if fuel comes out.. easy ! Prop stopping and engine tryng to go backwards
might be several things but mis-timed is most likely I think. If its really out
, it will run backwards (if you want western prop direction .. !) but I suspect
its not designed to do so properly! Can anyone quote me for a complete engine
overhaul of a CJ6 at all ...? Would need some level of paperwork for airworthiness
too. Back yard rebuild not acceptable as yet. Thanks ,
Matt
