I have a farmall 100 and it has become very difficult to start- seems to flood. If I adjust the screw on the carburetor, it seems to sometimes help but then becomes hard to start again and seems to be flooded. Any ideas? Thanks

Sounds like the carb float is not regulating the fuel level in the bowl. Possibilities include an improperly adjusted float level, failing (leaking or binding) float, a worn out float valve, a bit of trash caught in the float valve, etc.

Unfortunately you'll need to go inside the carburetor to determine the cause. Fooling with the external adjustments is not going to fix it.

First off when was the last time you serviced the air cleaner and made sure it was not full of water/dirt. Also look in it to make sure it is not full of dirt dubber nest etc. Next pull the rubber tube off the carb to air cleaner and make sure it is still good and not clogged up. Then try this. Pull the drain plug out of the bottom of the carb and let it flow a few minutes catch the gas to look for dirt/water etc. It maybe as simple as a little dirt not letting the float needle to seal so it flood easy or a clogged air cleaner

The idle circut soulnd like its plugged. The screw at the top of the carb wont help in starting and the one on the bottom is for power like and doesent help for starting. When the idle circuts are plugged in those carbs it does make them hard to start without flooding.

May also be a needle tip going had. Ethanol likes to eat needle tips.

Baloney!! I've been using ethanol for over 30 years and never had a fuel related problem in anything. Where do you guys come from?

I've never had an ethanol-related failure either. All the pumps are marked 10% ethanol, and my truck's gas mileage acts like there's ethanol in the fuel.

Pulled a viton tipped needle out of my Super A carb that's been in there at least 6 years, with ethanol gas the whole time. No sign of erosion, and hard as a rock. I thought it was supposed to turn into goo at the mere mention of ethanol?

Maybe the ethanol here has fewer impurities than other places? The toxins in poorly made moonshine that make you go blind if you drink it, you know?
