Thanks...good confirmation that my AC issue with the Honda and the Easy Start is normal for those of us at 6000 feet. Bummer. I still love the propane generator, so much cleaner to deal with as you mentioned. I do wonder though if the gas version would have made a difference with the AC at this elevation.

Your solution is an excellent one, but I'm a little ways off from a kick-ass solar system like you have!

Also, re: my question about leaving the low altitude orifice in, at higher altitudes to see if I get more power, yielded this response from Genconnex today:

'Peak power is achieved when you get the correct fuel/air ratio

As you go up in altitude, the air is thinner. If you don't install the
proper orifice to reduce the fuel commensurate with the reduced air then
your generator will run improperly (too rich) and will not produce the peak
power it's capable of at high altitude. Leaving the low altitude orifice
in will also likely cause your spark plug and engine cylinder to get carbon
deposits on them due to it burring too rich.

On the other side, if you keep the high altitude orifice in and run it at
sea level the engine will run too lean and may cause overheating. It will
also not run properly nor will it put out peak power.

This is the same for gasoline or propane.'


So, not switching out the orifice at altitude will hurt, not help.

One last thing, in case you missed it along the way. Genconnex recommends the Champion Z9Y spark plug, with a smaller gap of .020-.022, versus the larger gap that is OEM on the generator from Honda.

We also recommend using a spark plug gap of 0.020-0.022” as propane requires a slightly higher energy for proper combustion. The original factory gap for gasoline is approx 0.028”-0.030”. Leaving the gap larger (especially on the Honda EU3000is through EU7000is) will cause noticeable sputtering at no load and ECO mode. Here is our latest recommendation for spark plugs as of 6/1/2017 for each unit: EU2000i Champion Z9Y (was NGK CR5HSB but showed recent poor performance in hot weather)

Thanks

PK

Do any of the newer multi use conversions use a mixture block or are they all using a non-adjustable orifice tube? 😳

I use the Genconnex concession which is not adjustable other than the ability to manually change the orifice for high / low elevation.

I like it because, its "stealth" and gets neatly bundled inside the generator shell

Definitely is a cleaner looking application...my work around when I did the UScarb conversion 11 yrs ago.
A spare $12 front cover and a 24gal ActionPacker, with a possibles bag for the LP stuff.
A little bulky, but werks ok.😏
