pure synthetic burns clean with NO little to NO hydro carbon emission
cheaper weeder oil has natural oil in it.
I said "Probably can be done". As you pointed out, there is a difference between what is possible and what is practical. I think that is why four-stroke powerheads for weedeaters are coming onto the market.
FWIW, I own a few four-stroke engines (model airplanes) that use pre-mix (methanol based) fuel and don't have crankcase oil. I also have a 50cc two-stroke gasoline engine that burns 100:1 synthetic mix. The later burns much cleaner with no perceptible smoke or exhaust smell. But, it also costs $600 just for the engine.

Professor95 & MrWizard,
Thanks for the kind words. Unfortunately, I didn’t have the space to use the glass door from the microwave. Interesting idea though!
I hope that someone takes the time to answer my genhead temp request. This has been a fun quest for me. It helps fill the need to use my engineering skills during retirement.
As you may remember, my first enclosure completed about 2 ½ years ago was just an aluminum case with noise absorption matting on the interior walls and an open bottom. This worked fine for my 3 month Alaskan adventure in a cool climate where A/C wasn’t necessary very much.
When I return back to AZ, I added an automatic transfer switch and a small cooling exhaust fan to the top of the enclosure. That fan was very inadequate and is now re-purposed into the booster cooling fan for the genhead.
My next iteration added the 300 cfm exhaust fan to the side of the enclosure. It worked very well, but I was still concerned that the AVR & genhead weren’t getting enough cool air and hot air re-circulation wasn’t controlled with the bottom still completely open. Of course, the gas tank was still in the enclosure and was also a concern.
That led me to the latest design detailed in this forum. This will probably be the last enclosure design for the generator except for the improvements noted. It meets my 5ver electrical needs in the AZ climate.

I know this isn't a 3000 watt Chinese genset, but it is probably Chinese built. Check out this offer from Costco.

If I was just starting my generator quest, I would probably buy this ONAN 4300 watt electric start inverter genset rated at 62 dBA for only $1300.

3800 watts of power from an inverter genset, nice, but i don't think it will fit in my RV genny compartment

Fired up the little 1500 watter, it ran good, tried air conditioning fan, it worked, TV it worked, microwave (900w) it didn't. The front panel of the MW went crazy, but luckilly it still worked when I went back to shore power. I did notice that the light inside the mw flickered when genny was running, mw was not on and door was open. Do I need to plug mw directly into genny to get it to work? Is coverter/battery charging taking up too much power?

Hmmmmmm - $1K discount (that's a biggie!)- almost wonder why.
The $1300. price gets it "close" to various Yam & Honda models
- with proven reliability & service.
But then . . .$1300. = 3 or 4 Champs
or 1 with $$$ to spare - also with proven reliability & service.

Charging a 12 volt Battery and making an output power cord:
I have a Champion C46540 for back-up power. I did a search for this question but didn't get much. It has a 10A 12VDC output with the alligator clips to charge batteries. The users manual mentions to not charge deep cycle batteries. What is the difference?
Is there a way to make a 240 VAC twist-lock female into 4 120 VAC power cord, at home? I’ve seen (or think I’ve seen) these with higher priced home-type generators and on the Internet for about $100.

Bobandcat,
Great job. I measure my genhead temp by sampleing the air temp exhausted by
the genhead fan....Hmmmmm......
Maybe I'm approaching this all wrong.
The glass door thing is a cool idea though....

at 10 amps max charge, it won't make any difference if the batteries involved are deep cycle or regular starter batteries
what do you mean by (4) 120 VAC power ? do you mean a (2) circuit 4 way box with (2) duplex outlets connected by a 4 conductor cable (red,blk,wht & ground) ?
I think you will get better power use and regulation using a dogbone plugged into the full power duplex outlet
