Thanks,
Yes!

The Garretson demand regulator will blow out if you apply more than 11" water guage LP pressure to it. Thus, you need a high pressure regulator (preferably a 2 stage one) that must be in the supply hose to the pancake Garretson at the genny.

Ah, finally, clarification. Thanks to all.

Tank to high pressure regulator
to hose
to generator regulator into the generator.


Although the high pressure regulator could be at either end of the hose.......

I do wish that US Carb would put this documentation on their website.

Got my parts.......

Well, I received all my parts back from US Carb today. Fortunately I did have them mount the engine regulator on a spare generator door and it includes a tachometer. There are a lot more pieces than I expected, but I think they sent me ALL the pieces I'll need. The pieces look exactly like in Robert Cross' pictures.

Unfortunately US Carb tech folks don't respond to email or phone questions, so I must ask for help from you folks.

But I do have a few extra questions.
1. booklet says that brand new generator must be run on half load for 90 minutes using GASOLINE, before starting to use propane for the first time.
2. Even when using propane for fuel, the gasoline tank must be at least 25% full with gasoline.
3. There are guidelines for initial adjustment of the regulator load block. I'm worried about resetting the start point since the instructions say 'below 9hp generator'. This is a very small 1000 generator.
4. I have not yet located the propane primer.

Anyone familiar with these restrictions?
Thanks,

If your generator is new it is required that you break it in on petrol.

As far as keeping the tank 25% full, what I plan to do is use a small amount

of fuel stabilizer and run the Gen Periododically just to be sure that if you

ever need to run on gas everything will be working properly.
STA-BIL
If your Yamaha has a good sealing cap you shouldn't have to worry about

fumes or leaks. You must to remember to put a fuel shut-off on the gas

supply line to the carb to prevent a vacuum leak into the carb

vunturi.

I think what they recommended on the load block was 2 1/2 turns out from

fully closed. Not even close, you can see in the photo how far out it's turned. Just adjust mixture with the tach to best idle,

then check again under max load. (used my co-pilots hair dryer on high,

1500 watts, low setting was 800w which would be good for your 1000)

Just don't get it dirty like I did, now I've got a Generator test instrument

for the tool bag

Your primer button is located on the back side of the regulator, I've got a

foam R/C car tire insert around mine to help keep the dirt out.

You can see it in this photo. Just slide a finger under it, give the button

a couple quick pushes and your good to go, Keeps others from pushing it

by mistake too.

Robert.

Thanks for your guidance. One difference between Honda and Yamaha 1000 generators is that the Yamaha has a build-in gasoline shutoff valve.

FWIW, when I got mine, there was NO documentation (at least that I saw)that suggested running it on gasoline to break it in. Mine has about 30-40hours on it and it's all been LP...still on the same 20lb tank too.

I don't think that mine even has a gas tank anymore. I bought my Yamaha direct and pre-built from US Carb to run on LP. I'll have to check and report back.

Promise you won't tell anyone......

When I was setting the LP mixture I used my wife's 2 speed hair dryer to supply the load, about 1500 watts on high, 800 on low. I didn't know this at the time but if you ever use one of your partners "tools" for anything other than what they are designed for they can never again be used by anyone of the female persuasion. NUFF SAID!!

plus I got it dirty
