[MRCA] PU-181 Generator Fuel/Lube

[Chris Bowne]

The antique engine guys on the smokestak  forum might have some good advice on this.  I have run 16/1 mix in my GRC-9 PE-162 no problem using current manufacture 2 cycle oil.  Great multi tasking genny...it's a genset AND a mosquito fogger!

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.
