Why do my idle jets keep gumming up?

[DClark]

They get a white-ish looking film around the orifice, looks like elmers glue! On one, I good barely blow through it thne phew- blew it out. Is there something made of plastic in the carbs that is dissolving?

[kevin2502000]

That sounds like aluminum oxidation, what did you use to clean them with?

[Kreylyn]

Fuel mixtures... there is a white/beigeish residue left over in the carbs from running fuel mixtures that include ethanol. It's especially bad around the slides if you pull them.

Is there anything I can do to reduce it? Any additives that might help?

Find fuel sources for less/non mixtured fuel.

I don't know of any additives that will resolve this issue alone... cleaners can help to prevent buildup from clogging things for fuel flow if used regularly, but I don't think it will prevent it from happening.

Krey, Have you found a brand with no or less than 10% ethanol?

It will vary state to state. I have not found a good source myself in NC, but I know that gas here may have less than say... TN... where I've noticed a significan't difference in the gas from there in comparison.

mixing in a little seafoam my help

Seafoam is 30% alcohol.all the gas in my area is the same so I am screwed

[Londob5]

Nope, it's a pet alcohol mixture. Pet alcohol and pet ether are really good hydrocarbon solvents (I use something similar all the time to clean the injection needles on our GC-MS).
It's different from the 10% ethanol additive that you may be referring to.

I read one time that adding acetone to gasoline will improve gas milage (results vary/2 ounces per gallon I think?). But, I also read that the gasoline has to be ethonol free for it to work properly. Therefore, I asked a gasoline truck driver if he knew of any stations that have a Non-ethonoyl mixtures. He told me of one gas station about 20 miles from me. He also said that the company he works for uses a Non-ethonoyl mixture for pumps/tanks that have water in the tank under ground. He said this one paticualr tank has about one inch of water in the bottom of the tank.
So, if you know or see a driver at the pumps one day just go ask if he can tell you where to find non-ethenoyl gas.

DID I SPELL ETHENOYL RITE??

I'm in the industry. Drivers don't know sh!t.

1. It's quite easy to remove the water from the tank.
2. The pick up tubes for the pumps are typically 6" off of the tank bottom, to prevent the suction of all the crap that is eventually found in the tank sump.

I actually have been looking and the best I find in NY seems to be 10%

I dont want to look like I'm talking $#!T here (well maybe alittle) but I just got home from work , its 3:51 in the mourning, and on my way I seen a tanker at the filling station so guess what I did? Well boys and girls, I ask the driver if he knew any local gas stations with non-ethanol pumps. Boy oh boy, if you live in the Raleigh area I have a surprise for you ! Not only did he tell me about several pumps fairly close by but he also said the exact same reason for doing so is water in the tanks. Then he said the gas station is allowed up to 2 inches of water before its called in to the authorities for servicing. Then he said that sometimes the station will advertise on a sign that they serve ethanol free gasoline. Reason is mixxing ethanol gas with water gasoline can cause a dangerous mixture for your engine.
Oh I mentioned this thread to him and my new friend says he's driving a truck to pay his way thru Veterinarian school.
Thats all I have for ya .
Have a good one
