So, for the past 6 weeks i have been cleaning the idle 55 jets on my two weber 40s 30mm vents. Ive cleaned out the clear jelly from the tank to were the car is drivable but cannot get it to last more than about 20 miles when the webers develops poor idle transition. The mains 130 run fine. All plugs are a light tan. After i cleaned the tank it does drives much better, but it stills does not rev through the idle circuit properly after every carb cleaning and a 20 mile drive. I'm just pumping more gas/water into my tank.

I seem to be in an impossible situation since after only two fill ups, I can see the water droplets in the bottom of the tank, again.

The car runs great after i blow out the idle jet and mixture circuit.

In fact i can tell which jet is clogged just by twirling it's mixture needle
and not getting an engine rpm response at engine idle.

So, can someone respond, please, with how they are dealing with this
ethanol fuel?

my search is leading me to a boating marine solution, maybe.

If the idle jets are clogging it sounds like solid contamination rather than water. You might try taking the gas tank to a radiator place, have the tank boiled out, flush out or replace all fuel lines and install a really good fuel filter. If you are sure it's a water problem, there are some additives you can get to help with that.

thanks, every time i do a cleaning i do not see any contaminants. There was a soft clear jelly in the carb bowl that i swabed out with q-tips and lint free shop towels.
I also did it to the inside of the tank. The tank is still good, it even has a clean green coating to it. The carb bowls have not recoated with this clear jelly.

Yes it is a idle jet clog. On some occasion i gently blew trough the jet and noticed a small pop.

I'm defiantly getting water/GAS and it may be of the jelly H2O/ethanol contaminant from my local fuel stations.

I'm reading that additives will make it worse, since they are alcohol based and clean the system then dump it into your carbs. I'm also reading that additives work fine with fuel injection pressures but not with the low pressure that a carb works with, thus easy clogs with older cars.
still reading all i can find

thanks
