| Subject: | Re: Wet Dog Syndrome On Shutdown |
After testing the other night at the hangar, the idle mixture was too
rich at about 150 rpm, rise. I got it set correctly now at 50 rpm
rise. That helped a little on the shutdown shake.
But...
I discovered another issue that I thought I'd tackled a while ago. The
top passenger side engine mount seems to be "knocking" again. Early on
it was doing this and I had found out I needed another washer because
the nut was running out of threads and wouldn't fully "Stack up" with
the spacer inside the Lord mount. Well, know that the shutdown is
cleaner I can now hear the knocking again. I think it is the spacer
inside the mount hitting the sides of the durometer inside. At least
that's the only thing I can think of it doing. I don't know if it's an
alignment issue or what, because it is only the one mount, not all
four. I placed my hand on the mount when it was at idle and you can
feel the knocking. It also resonates through the engine mount and you
can hear it inside the cabin.
I have a call into Lord to ask some questions. I am wondering if I need
the J-3804-28 (which has a different silicone/rubber wrapped spacer
inside) instead of the J-3804-20. I am hoping I don't as they are about
$250 each. I just can' figure out why only one is having the issue.
Unless it's the weak link and is flexing the most during
idle/start/shutdown.

Geoff
Could you please email me, as I'd like to ask you some questions re the installation
of your Carbon fibre panel and if the angle which spans the cockpit has
to be removed or trimmed please?
Warm regards
