[MRCA] PU-181 Generator Fuel/Lube

[Tim]

OK Wise Guys - here's a question for you regarding engine oil and
concentration.

The PU-181/PGC-1 is a 2-stroke gas generator rated at 300W, 240/120 VAC.
It uses a Jacobsen GE-12F engine.  The generator is designed for the PGC-1
TTY terminal but also for general purpose use.  It has a completely
shielded ignition system - it is radio friendly. This same engine is also
used to power the GRC-9 DC generator adaptation.

The placard on the fuel tank advises a *16:1 fuel-oil ratio*.  It states to
use SAE 10 weight below 32 degrees F and SAE 30 for operation above 32
degrees F.

However, the Tech Manual TM11-943 "Engine Generator PU-181/PGC-1" (US Army
1951) states to use a *32:1 fuel-oil ratio* and it says to use SAE 10 lube
oil, it says nothing about SAE 30 or temperature.

So regarding mix ratio, which is it?  I don't know if there were any
post-1951 tech advisories that addresses this apparent discrepancy.

Comments?  Thanks
Tim
