carb main settings

[souNdguy]

now that we've been using this paint thinner gas for about a year now.. I have found that I have prety much had to adjust all my carbs just a hair richer.. IE.. 1/16 or 1/8 turn ( at most ). any of you guys seeing this? or other observations, other than this new corngas is junk?

Actually had my flaot valve stick on my 850 with a zenith carb.. it's never done that before.. found 'gumy' deposits.. reminds me wht I have seen in other ethanol gas/ carbs with problems

just set mine where they run to suit me.......don't care about number of turns.

In doing that though.. do you feel that you are having to adjust it a lil richer than you would straight gasoline?

I wonder what our high elevation people have noticed?

"I wonder what our high elevation people have noticed?"

Sounder:

I live in Castle Rock Colorado at 6,450 Ft. Tell the truth; I have noticed no change since the ethanol has been added to our gas (10%) at 85 octane. I can let the stuff sit for months and it is still good. Maybe it is a difference in the way it is refined or blended or maybe the lower oxygen levels. I will say that when I get visitors from the flatlands, they tell me their cars run poorly for the first fill or two up here.

I don't seem to have any problem burning anything in my N, old gas, new gas, gas sitting in it for two or three months, no additives.

It faring right up, but the engine is in good condition, and WILL outlive me, I made sure of that a couple of years back.

No trickle chargers, no 12v.

Now I do have other things that I have problems with, like the kids $500 chinese 4 wheeler for one.

Lots of times I have to open the carb drain for a few table spoons to get it to even run again.

Yep - alcohol is not near as good an internal combustion fuel as gasoline or diesel. Idiots in congress have taken food out of our mouths to make chittier fuel - but won't let us drill - no sense at all.

Same here. I kept having to hold the choke out and thought it was just because of the cold. Then when it got warm I found my self still holding the choke. Then I moved the big screw about 1/8 and all was fine. Thanks for the explanation. I was hoping it wasn't something bad starting to happen with the old machine.

I agree, I've left mine from September to middle of May, more than 1/2 full old gas , fires right up first time , no stabilizer, nothing.
My property is 2900 ft compared to 400ft where I live.

less btu's inthe fuel..so it makes sense that it will be leaner. plus in wet areas.. the fuel will now grab water due to the alcohol..

that's both good and bad IMHO..

From those more in tune than I!

"Gasoline is an organic product. Like any other organic material, gasoline begins to deteroriate once it is exposed to oxygen and sunlight. This may cause the lighter, more volitile molecules to evaporate out of the fuel making it harder to ignite. Once the lighter components evaporate, the chemical properties of the fuel have changed radically. The gasoline becomes corrosive, and particles of sticky gummy residue form. Ethanol further enhances and complicates this chemistry of gasoline and causes it absorb moisture from the air."

And I might add here in FL with much sunlight, moisture and oxygen these gummy and corrosive results are staggering. CO has a definite advantage for ethanol useage.

Can't really comment because we've had 10% EtOH in gas for more years than I've had old ford tractors. I do find a need to change thnings from season to season.
