    My son and I pulled the Holley carb from his car to do some work and we flipped it over to drain the gas out as much as possible. I am not sure if we pumped the accelerator pump or not. After 3-4 months, we put it back on and the accel pump was not right. Some brown honey was oozing from the nozzle.

    So a quick disassembly followed, and the only place where the fuel had broken down into gum was found was right up in the nozzle. It was easy to clean out. But another few months might have been a different story.

    The fuel being used is Shell premium (V-Power). If took just 3-4 months sitting in a garage through the summer for this little bit of residual fuel to gum up and break down. You just can't be careful enough with this new fuel.

    Any of it with ethanol is horrible. Although it is more expensive, I have gone to 100% gasoline from a local station. I can tell the difference in how the truck runs ans can honestly see a difference in mileage.

    Stuff is brutal on the Mikuni carb on my chopper. When I park it for the day I always turn the petcock off and run it til it stalls. Last needle/seat I put lasted about 5500 miles...

    You should never use ethanol gas in anything that's not post 2004 ish...

    It is highly corrosive to systems not designed for it and turns to sludge super quick...

    It is the main cause for fuel pumps going out...

    I have had two 90's vehicles throw fuel pumps due to this issue...

    Never again.

    well it sucks here cuz all gas stations must be 10% ethanol. I add Lucas ethanol additive - expensive but it helps. pure gas here is $10 a gallon. and the stupid government behind this crap ignores that corn is used to make ethanol when people in the world are not getting 3 meals a day, and farmers use like 2 gallons of gas to make a gallon of ethanol

      We did find that the Shell V-Power ran very noticeably better in this engine than the local premium non-ethanol. We'll start keeping using fuel stabilzer as needed, and put in the non-ethanol stuff when we know the car will sit for a while.

      We dumped the tank; the fuel looked like husky piss! LOL

      I've done some checking after having more then my share of fuel related problems in older vehicles. Even the fuel that says NO ALCOHOL can still have up to 10% ethanol and they can legally say ALCOHOL free! I ALWAYS spend the extra 30cents and get the "non ethanol" blend. Noticlibly better mileage and the engine runs several degrees cooler. Ethanol is absolute POISON and destroys carburetor s,fuel pumps,etc! It's all a government program, if that tells you anything. Seafoam helps as does the lucas ethanol additive. Spend the extra coin and save yourself a lot of headaches
