Honda EU2000i Stops Before Empty

[Al and Missy]

I have an older EU2000i which I have used on propane for the last several years. I don't remember the last time I used it on gasoline. It decided not to start on propane. Long story short, it had no spark. I finally diagnosed it to the stator which I replaced. I had spark, but still wouldn't start. I decided to eliminate the propane system as a component of the failure and filled it with gasoline. It still wouldn't start but after a good carburetor cleaning it started and runs fine, except.....

It shuts down while there is still gasoline in the tank; there is only a little, maybe a quarter of an inch, but I would have thought the way the tank is shaped with the line to the fuel pump at a low point, it would completely empty the tank.

Is this behavior normal?

Thanks,

Al

Normal

Thanks! Now I can try to figure out what is wrong using propane.

Start with the tank OPD valve & regulator.
Low pressure regulator, crack in supply line.

I've always started our 2000i on petrol just to confirm operation and prevent carb gunk.
Drain carb for storage.👍

Bob, personally I suspect that even draining the carb won’t clear out all the funk that ethanol laden gasoline can leave.

I flat plan to never run my dual fuel genset on gasoline. If I had to, in an emergency I’d probably be tearing it down for a thorough cleaning to get all the ethanol schmutz out of it. Let’s hope that never happens.

Propane does not generally leave any gunk behind. It’s a lot cleaner than any liquid gasoline. Even though the Champion apparently has an automatic dump valve to purge the carb of liquid gasoline I’m not convinced it won’t leave some behind to gum up the works or cause lingering corrosion from ethanol. It’s bad stuff on carburetor parts and tiny jets.

It always fires up on a few second of cranking on propane. At worst I have tu pull the choke out on the first few turns.

My bad...I'm so used to it I forget...e-free in everything.. We have quite a few around here 'cuz of the boaters.
I use e-free in all petrol powered stuff.

When on the road with the AS the Burb really doesn't care. We use the petrol in an emergency around the house because it's more convenient, no bottles to lug and the AS is too far away. 15yrs SFSG.

In my experience the biggest concern with ethanol is that it holds water in suspension in the tank.👎
The Ethanol in E10, E15, and E85 is a serious solvent / degreaser / cleaner. Ethanol scours and scrubs varnish, gum, sludge and dirt deposits.

If the funk is already in your system the E could free it and funk everything all up, no funk, no problem.

Bob is correct. Ethanol in and of itself does not cause fouling. If the gasoline base is blended properly and with (top tier) detergents.....AND....is stored properly, it isn't a problem. Here in Illinois, ethanol was introduced in 1980. I have NEVER had an issue in any of my 2 or 4 stroke engines. Ever.

Did you remember to open the vent on the gas tank cap?

Update -
Gasoline problem solved with a carb removal and cleaning.

Propane problem diagnosed to regulator. Ordering new one. Regulator settings not stable. Instructions say not to use the choke when on propane, or regulator may be damaged. I'm not sure but I may have done that. I took the regulator apart but didn't see anything significant.

Glad you got it solved. 👍

Your LP conversion doesn't have a purge button to get all the air out of the lines before trying to start?
