Something is not in proper tune somewhere or as previously mentioned, maybe a fuel leak. First and easiest thing to check is the choke to see if it is opening all the way at operating temp, next check the mechanical advance on the distributor ( turn the rotor by hand and let it go, it should spring back) take the rotor off and put a few drops of oil on the wick inside the shaft under the rotor. If everything in those two areas are OK then I would look for a leak, fuel pump first, if no sign of it leaking externally put the dip stick and smell it to see if it is leaking into the crankcase (not good for bearings) also if you a running the Solex check the ventura boosters to make sure they are secure and lastly pull the top off the carb. and check in the fuel bowl for a little glass ball.
