Is there a point in running E85. Ethanol runs cooler so you have to burn more to produce the same amount of energy. Therefore you burn more quanity of fuel. therefore you burn more gas. producing more polutants than if you burn straight gas. Help the enviroment stay away from Ethanol when ever posible. Bill K

Ethanol is much better than methanol, but it is still hard on rubber parts. You will need to richen it up and make sure you drain it out if you aren't going to run it for a while.

Shouldn't be too many rubber parts on an old LB to worry about.

May have to open the needle a little farther, but probably not as much as some think, especially if you're just running the engine and not powering something else with it under a load.

I tried running an old Witte I had on E85 -- it ran ok, for about 15 minutes. Then it stopped. Turned out that the E85 cleaned all the gunk out of the gas tank and left it in the fuel line and mixer. So I used the rest of what I had bought as a parts cleaner.

Out of all the engine's I have, the only one I have had trouble with RUNNING modern fuel ,is a very low hour 3-5 LB.I have trouble with the exhaust valve sticking after it has run for quite some time.The valve guide's in this engine are extremely tight where as in most of these engine's they are pretty loose.I think on this one,if I want to run it & not add lead subsitute, I will have to ream the valve guide just a hair & it should take care of it. Anymore I use regular unleaded instead of any ethanol blend because of the problems if you leave fuel in it.As far as E85 I wouldn't even consider useing it in my engine's.

I just run whatever is available locally, whether it's 87 octane unleaded with 'up to 10% alcahol', E10 that some claim is up to 27%, or if I have the money to buy it with I occasionally run 105 octane racing fuel just to get the slower burn rate (which is how it controls detination in high compression engines) and make the old engines run smoother at low speeds. It takes the jump out of them when they fire.

I've never been afraid of ethanol and haven't had any problems with it in anything I own, but I don't often go out of my way to use E85 other than to prove that I can once in a while. I think the last time I used it in one of my old engines was in my 6hp Fairbanks Z, and it worked just fine in it.

I've never used any additives in any type of fuel other than the occasional bottle of fuel injection cleaner in my car or truck

E-85 is nothing more than a "filler".

If it was up to me, i'd get rid of all that fancy crap and put GAS the way it's suppose to be.


And lower it back down to 2.50 a gal.

BUT...thats just me

I've run my LB on 10% methanol many times with no problems. I don't any more simply because I've painted in with enamel and avgas does not eat that like the 10% does. I have another engine running on 10% as well, and no problems with that one as well.

Methanol is NOT added to commercial gasoline. Unlike Ethanol, combustion product is toxic.
Are you adding "wood alcohol" on yur own?

Methanol has been added to commercial fuels in this country in the past. That practice ended in the 90's and caused many problems in older cars. Yes, I have added methanol myself simply to use a quantity I had over from a high performance engine project a few years back.

We are sold ethanol blends at the pump but only about 3% I think.

My little LA always started on the first pull -- until. Tried E-85 for a couple of months and now it won't run at all. Have taken the complete gas line and tank apart but nothing. Had the same result with my Packard and my wife's IHC pickup. Ate the diaphrams on the two vehicles.

Leaving all the politics and environmental issues aside I would think the only issues in these engines would be the fact that it does tend to clean things and that it absorbs water. The water thing becomes more of an issue with things that dont get used regularly. But on the other hand since we are for the most part dealing with cast iron we dont have the same corrosion issues that most people face with aluminum fuel system parts. We also have a much greater range of adjustment so even with a little less energy in the fuel and perhaps some water we should be able to keep our engines running happy. In a lot of ways 'stale' E85 is likely better quality than what was commonly available when these engines were new.
