Need help the same spark plug keeps fouling up

[Dartalltheway]

I need help figuring out why my 1 cylinder spark plug keeps fouling up. It gets saturated with gas and won't spark. I recently got a 1920 Holley 1bbl and rebuilt it, but I don't know if I got the float right or the air/gas mixture screw in the bottom of the carb. Any help much appreciated.

try a compression test and check it to the other cylinders should nt be any more than 10 to 15 psi difference . it may be a valve problem

Bad cap or wire maybe. Check the simple things first.

If it were the carb all the plugs would foul.

i agree with badsport , you must be getting a misfire at that cylinder. if it was a carb issue ,you would have more than one plug fouling like snake says.

Well I fix the float and the entire car is running near perfect, but I'm going to have to wait and see if the plug fouls again.
