Ethanol

Post by Rut Row » Sat Jun 09, 2012 2:46 pm

The P3 sidecar has 4 Mikuni VM26SS carbs on it. Bucho and I were told to avoid using any fuel with ethanol. In fact, I drained the tank in Canada and refilled with local ethanol-free gas.

I was hunting for ethanol-free gas around here and there isn't any!

However, on further research, it appears that my fears may be over-blown. I was reading that on these VM carbs, all I need to do is replace the float valve needle and seat. The carb gasket is paper and okay.

The fuel pump is a modern pump so it should be okay. Same for the pressure regulator. I've got ethanol resistant fuel lines (have a few still to replace).

So, the big question becomes should I run some Sta-bil just to be safe?

ANy carb wizards/ethanol experts out there?

Yes, put it in or buy race gas. I have a buddy who has a repair shop and he told me to put Sta-Bil or Star-tron in anything that will sit for a week before used again.VP Racing Fuels make a fuel that is not race gas but is better than what you can buy at the pump. Cheap insurance unless you like working on carbs.

No need to worry about ethanol if any of these places are close to you

All of my toys get fed ethanol free gas from a local station :thumbup:

I've checked the "Pure Gas" websites. The data is old. Most are on the eastern shore anyways. Usually boat dock gas stations have it.

Eastern shore ain't close - the local airport doesn't sell ethanol-free mogas either :wallbash:

I've been using av gas in all my stuff except cars. Lawn mowers & weed eaters start so much easier, & its supposed to last two years. I pickle stuff with it now for the winter.

Cheap compared to any of the VP, Cam 2/Sunoco, etc. offerings. My Scorpa can't have ethanol - it destroys the tank. I've been round and round looking at all of the options for a couple of years now. I'm currently buying VP C9 (unleaded, 96 octane) at $12/gallon. It hurts, but it's a hassle for me to get 100LL and there are no other ethanol-free options anywhere around. I'm surrounded by marinas and not a one of them has anything ethanol free. Fortunately, 5 gallons lasts me ~ 2 months in the trials bike so the cost isn't significant relative to keeping fuel in a regular dirt bike or a road-race bike.

I never tuned the bike for the 100LL and as a result, it never quite ran right. Not bad, but just not as good as with VP SEF94 or C9. Lots of trials guys use it successfully. I used it all winter (10 gallons worth) with no problems.

Be wary of the stations listed as ethanol free on the web sites... I bought from one on the list and tested the fuel. It contained ethanol.
