Well, not fixed but frozen with rust. Takes a big vise and a bigger wrench. The
problem is common but I've never heard of an air start valve acting like this
without first causing start problems.
Since the valve is installed "upside down", moisture will accumulate there and
rust up the works. I have 2 different start valves and swap 'em out from time
to time and OH as best I can. At maintenance time I'll load up the incoming air
line (on the bottom) with air tool oil. Sooner or later the lower workings will
wear out from me removing rust and then Doug will get a call for a new unit.

| Subject: | Oil Temperature Guage on Yak 55M |
--> Yak-List message posted by: "Royden Heays" <heaysr@telus.net>
After many hundereds of hours of well behaved indications the oil
temperature guage on my Yak 55M has begun to flicker right up to full
deflection. This occurred for the first time yesterday on start up when the
oil was known to be cool. The guage is the standard Russian guage that goes
with the M14P on all the Yaks I have seen.
Any pointers?

WHO MAKES THE BEST PATIENT?
Five Surgeons are discussing who makes the best patients to operate on.
The first surgeon says, "I like to see accountants on my operating table,
because when you open them up, everything inside is numbered."
The second responds, "Yeah, but you should try
electricians! Everything inside them is color coded."
The third surgeon says, "No, I really think librarians are the best;
everything inside them is in alphabetical order."
The fourth surgeon chimes in: "You know, I like
construction workers...those guys always understand
when you have a few parts left over.
But the fifth surgeon shut them all up when he observed: "You' re all wrong.
Politicians are
the easiest to operate on. There's no guts, no heart, no brains and no
spine, and the head and the
ass are interchangeable.

Check with Doug Sapp. The points on the Chinese mag are interchangeable
with the M9-F mag.

It may very well be the oil temperature sending unit. Don't assume it's the
instrument without checking out the sending unit.

Hi Royden;
The oil temp gauge (and carb air temp) are Wheatstone bridge circuit
instruments. The snag you describe suggests an intermittent open circuit
somewhere in the system. It could be in the instrument, the wiring harness,
connectors or internally in the probe.
If you select "oil out" does the problem continue? That uses a different
probe and harness (but to the same inst. connector). You can swap the probes
for trouble shooting, all three are identical,
An open circuit will cause a full scale reading. Good luck.
