“Please post this picture, taken this afternoon, Thursday Sept 17 after I made it to the top of

Berthoud Pass 11,307. My house is at 8665 ft, which makes the climb over 2750 feet

in approx 15 miles, average grade over 6%(it’s downhill to Fraser, then up)

The GEK performed flawlessly going up hill, but I always have trouble going downhill,

and had to boost it with gas a few times (3 or 4 ticks of the electric fuel pump)

It’s like the throttle being closed down strangles it.

But it flies uphill (steady load- wide open – 2nd or 3rd gear,

and I even get some reaction from my “carburetor”- the butterfly valve.

Usually, I am on full woodgas- I suspect I have some vacuum leaks.



Here are some photos we just recieved of Frank Mannix and his plans to run a GEK-powered VW Thing--nice looking trailer, Frank!

Very Nice!
I knew about the Mountain Pine Beetle Invasion, but, c'mon, Frank, this is literally a mountain pine (burning) beetle!
Ja, I know, it's a Thing, not a Beetle, but close enough
I'm really impressed with what you have accomplished here. I would love to see it running.

Is that your fuel box mounted on the back?

I originally mounted it for that reason, but it turned out to be unneeded as I wasn't using fuel that fast,
and I generally don't go more than 30 or 40 miles on a trip, and I am getting nearly 10 miles to the inch measured on the side of barrel hopper.
I have put around 600 miles on it in the last two summers, and am getting ready to rig the GEK to run a generator, one advantage of having the GEK
on its own trailer.
PS This summer, my 20 year old daughter showed an interest, and now she is the only other person to have fired up and driven our unit.
