| Subject: | Engine roughness at low power, 82% RPM? |
One of the M14Ps I fly seems to be rougher (not quite a popping sound but different
than usual and has added vibration) close to landing. 82%, low throttle (very
first notch on the Russian manifold pressure gauge or so). Both have MTV9
props which tend to prop brake during these conditions but the other engine is
fairly smooth in comparison. It does have less than 200 hours on the engine
whereas this one is about 620.
Any ideas?

Check fir intake leaks. Especially if it has an intake drain kit. Also check all
intake gland nuts.

Also check the condition of the manifold pressure hose and primer hose.

Thanks Dennis. I figured it might be an intake leak. Will do.

One more thing - is there an easy way to determine which intake tube might be the
culprit? Or might as well do the gaskets on all?

| Subject: | Virginia Bader framed pictures |
Guys,A bitter sweet decision but I sold my hangar/apartment at Windward Pointe
in Alabama this week. Four grandkids and a lot of flying lately made it the right
decision. I have a number of pictures that I bought from Virginia Bader through
the years. They include the following:
Air Force F-15 Nowhere to HideArmy UH-60 New Dawn (helo in Afghanistan)Navy F-4
Dragon SlayerMarine A-4s Triple ThreatRobin Olds F-4 coming off the steel mill
strike in N Vietnam Leader of the PackOriginal John Taylor oil of B-25s on the
RangerA Robin Olds montageP-51 cutaway
and four smaller pics of my heroes: Chuck Yeager, Robin Olds, Bob Hoover (with
his signature) and Bud Anderson (with his signature)
This is a museum quality collection. Many of them cost upwards of $1000 each. I
simply don't have enough room in my house for all of these and I want to see
them go to good homes where they will be appreciated.
Email me off line and I'll be happy to send a picture of any you are interested
in and to talk price.
Thanks

The only way I know is to spray the suspected area with propane or carb cleaner
with the engine running. But carb cleaner is flammable. Best to troubleshoot
this when the engine is cold. So if you use carb cleaner be very careful. What
youre looking for is the engine RPM to increase if there is a leak wherever
you spay.

You could use a propane torch but dont lite the torch. Just use it like a sniffer
and just wave the propane gas around the joints I will do the same thing with
a lot less danger.
