I'm looking to change my paint scheme, but only if I can copy the original scheme
of the Chinese CJ6B in service. Does anyone have photos of the 6B? I also need
information on the guns and bomb racks. Or if they even had racks.
Thanks in advance.

| Subject: | Oil dilution system on M-14P |
Does anyone use their oil dilution system for cold weather starting when preheat isn't available? We didn't use it on R1820's on T-28's , but taxpayers were paying for the engines! If not for cold weather starting, I've considered using mine to dilute the oil before shutdown for an oil change to help the 25W-60 drain quicker and flush the system better. According to the tables at http://www.yakuk.com/oil.xls it would need a 2 min+ shot.

No one that I know in the Yak community uses the oil dilution system.

That's funny but i was just reading about that a few minutes ago. The snip below
is out of the engine manual. Note item 3 (i assume this is due to the fuel
loosening up deposits?):
1. Warm up the engine for 5 to 6 min at a speed of 41 to 44 % (1200 to 1300 r/min).
NOTE: The engine with diluted oil is regarded warmed up and ready for flight,
if the cylinder head temperature is at least 120 C and engine inlet oil
temperature is not below 25 C.
2. Gradually increase rotational speed to 51 % (1500 r/min) and see to it
that the oil pressure in the main line is 4 to 6 kgf/cm . NOTE: If oil pressure
drops below 1.0 kgf/cm owing to excessive dilution
with gasoline during engine idling on the ground, drain diluted oil from the oil
system and fill it with anon-diluted fresh oil with subsequently checking pressure
with the engine running.
3. Wash all oil filters after first dilution.
CAUTION: IN THE COURSE OF DILUTION. AVOID ENGINE INLET OIL
TEMPERATURE RISE ABOVE 50 C AND CYLINDER HEAD TEMPERATURE ABOVE 160 C.
