I know many on the board replace their teapot carbs with something newer. For those that don't here is problem I'm having with mine that may help you in the future. My 56 with a 312 starts and idles fine hot or cold. It runs fine up to about 1/2 to 2/3 throttle, above that I get a smell of fuel in the cabin and the engine starts surging. I wasn't going to look for the problem as the engine is coming out in a couple weeks for new carb, ignition, heads, intake , cam, etc. However as the temperature around here has gotten warmer the surging has gotten worse and I thought I would check a few simple things to get me through. Checked plugs, on the dark side not unexpected with the symptoms. Timing 10 degrees with no vac 19 with. Decided to check the float level. After running the engine for 30 seconds or so I removed the top of the float chamber and checked the level. Fuel was 3/4 inch below top of bowl (should be 1/2 inch) but fuel was still entering bowl. This continued for 5 min or so. I first thought I had a bad needle or seat but discovered the fuel was not coming from inside the seat but from around it. I have since pulled the carb and found that fuel is leaking past the small fiber washer that seals the seat to the carb body. I will take the carb to work tomorrow and see what I can do to repair. I don't know if this is the cause of my problem but will post about the repair and if it helps after I finish. Mike
