Well that didn't go like it was supposed to... motor trouble question?!?!?!?!

I have a buddy that buys the VP racing fuel here in the cans for a decent chunk of change. He's running a 2-stroke though, and it's all pre-mix. That, to me, isn't a bad option. No mixing, no hassle, all ethanol-free. It's very expensive though.

Ironically, I have one of the only VP gas stations 15 min from me here in NJ. I stopped one time, hoping I could score some fresh ethanol-free racing fuel, but nope.

Another option: Rec-90 ethanol free aviation gas. They typically don't dispense to the public though. Typing this reminded me I have a client with a small airplane that I believe uses it.
The problem with ethanol is that it's Hygroscopic and can take moisture from the air if it gets exposed to air. So vented tanks will take moisture from the air and hold it in the tank. When I get done and I am gonna leave the motor for more then a week or so without running I hook up a small tank of ethanol free fuel. Even Tru fuel from homedepot is ethanol free. Then my system has no ethanol fuel while it sits. I keep the fuel tank vent closed and out of the sun.
 
Think you will enjoy this flyway a bit more..... where you headed? Wyoming right?

Yes, while WY is not a duck destination, neither is my part of the east coast anymore.

The area we are in is high, high, high desert with mid size permanent rivers and reservoirs. A lot of ducks breed there, which is fun to see families of gadwall, wigeon, swans etc... in summer. I'm moving for the big game hunting, but am hoping I can pull together some decent waterfowling when there. I am a pretty lazy duck hunter, I like the gear (the boats, the decoys, the dogs, etc...), but I don't push too hard, especially anymore. :) I'm easily satisfied if I shoot a few pretty ducks on my terms, on my terms being the key.

I put together this cutie for just that purpose (I've posted this before). I run the motor on it from when I see the launch coming back in through flushing the motor to give the ethanol free time to work through the system. Since it is only a gallon it is easy to deal with. Given the ice in the carb problems I had this year, I'm wondering how thoroughly it is removing the ethanol, but that is my best attempt and ethanol free won't be in issue again after march for me.

I think you might be pleasantly surprised sir. Great big game state btw. I have never hunted anything with 4 legs (except Coyotes) but my good friend who films for Kuiu shows me stuff all the time. How I have never delved into that area of the hunting world, I have no idea. But one day I hope to put some wild elk in the freezer. Good luck with the move sir and safe travels. Moving is a nightmare in general, across country, youre brave.

Not sure it could be anything in the carb. Severe cold makes all metal shrink. I am having an issue with deterioration of the internal fuel lines clogging up the carb. I replaced them all but still suspect inside the fuel pump are small bits of rubber. If anything makes it the needle and seat it will hold the needle open. Also the tip of the needle can get deformed and not make a seal. If you rebuild it make sure your floats are set based on the Yamaha procedure make mine just about level upside down.
