I have a 1949 8N that runs for about five minutes and then floods. The float sticks open. Any suggestions?

if the float is sticking open you will know it...
pull the hose off the air intake and gas pours out
and keeps running out the carb it's stuck open or has trash in the needle seat area keeping it
from closing.. you may want to check the float itself and make shure no fuel has got inside from a crack in the brass. ps: do not use compressed air to blow out the fule line while connected to the carb nor to clean the fuel inlet on the carb as you can
collapse the float and it will not (float).. don't ask how I know !!

If you're absoulutely sure it's the float sticking, you'll have to figure out why.Remove the float chamber from the carb with the carb still attached to the manifold. Turn the gas on and manually raise and lower the float and see if it's hanging up somewhere.When you lift the float the gas should cut off. If it doesn't, check the needle valve and seat for wear, damage or trash. If it does cut off the gas flow when you raise it, and there is no rubbing or binding as the float moves, then it may have a leak. Remove it and and check it for pinhole leaks(shake it an listen for gas inside). If it's OK then adjust it to 1/4" and reassemble.

Now, if you're not sure it's the float, it may be the coil. If the spark-maker shuts down, then you could mistake that for flooding as the unburned gas collects and stalls the tractor out.
