Hello all I am new to the forum, and am looking for some help with my autolite 2100. I am running this carb on my 1972 international scout. 266 cid motor. Due to the way these carbs are made I have found them to be excellent on trails in off camber situations. Anyway. I have rebuilt this carb several times using a rebuild kit for a 289 cid ford motor, but can only get 2 or 3 months out of each rebuild. After a few months the scout will not idle I adjust the idle speed up, and every time I can pull every other plug wire and it will not make a difference in the idle. Only half of the idle circuit is working right. Usually I can turn one of the idle screws in or out all of the way and it will make little or no difference. If I pull it off and clean it good and rebuild it will work fine again for a bit. This truck has been completely rebuilt from the ground up. New rubber fuel lines, new inline filter, so I don't know where if any trash could be getting into the carb. Any help would be great. THanks.

Upgrade to Fuel Injections man! thats what id do. or buy a brand new carburetor with warranty.
Fuel injection would be nice, and is in the work in the future, but for now I would like to get this one working. I see no reason why it should do what it does. ALso forgot to mention I am running a fuel cell, so no rusty gas tank.

if you rebuilt it a few times maybe it needs overhauled.

If your carb has a bowl vent, or a charcoal cannister, you could be sucking crap up through that.

Pulled plugs on cylinders that seem dead and they are wet fouled with gas???? The other plugs look good. abit more carbon than I would like to see, but wipes of with the tip of your finger and the plug looks like new underneath. I was hoping some oldtimer techscould help with this one. :bigthumbsup

Hello, Well I am an oldtimer for sure.
Here is a link to a great site about the carb
Autolite 2100 Carburetor Rebuild

Check it over to see if you missed anything.
Next I would run a filter in the line in addition to the on on the carb.
Lastly I would go one heat range hotter on the plugs.
A hotter plug should help burn the carbon better and last much longer.
Be sure to change just the heat range of the plug.

Just a few ideas from an old BYM....Print Dad
