[MRCG] PU-181 Generator Fuel/Lube

[Bjorn]

Hello Dennis.
On an unrelated matter, as I have been busy on Saturday evenings, can you please book me for a talk at SLO.
The subject will be "PRC-8/9/10 Radios". Talk and demonstration of the various hardware used with those radios in operation. Any time Friday, provided there is still a slot. I will bring 6 complete stations and remotes, test set etc. that then will be on sale Saturday.
I don't think someone has done this before. I know that Tim -CC is an expert on this, so I will ask him to attend, to be my support for related questions.
Thanks,
Bjorn

Good question.  I only have experience with the GR-9 version (PE-162)  
which is
a smokey little devil at 16:1,  I've run mine at somewhat lower ratios  
with modern
2-cycle oils with no apparent problems.
