[QUOTE="Pappy, post: 407359, member: 3278"] First things first. The ball will not remain hard once the engine has started as the ball is on the suction side of the fuel pump.....make sense now? Secondly, if you have fresh fuel it is probably Winter blend fuel which runs much different and not very good in warmer weather. If you have an idle mixture screw, richen it. Run the engine again. In addidion to WB fuel you are probably dealing with varnished up passages in the carburetor. Let the new fuel do its work to clean them up. Do not run the engine hard if it is indeed lean. Extra oil will help here in protecting the engine and cleaning up the passages in the carb. You did replace the old bad fuel....right? Not just dump good fuel on top of the old bad fuel?? [/QUOTE]
