I'm looking for some help from the experts.
Freshly rebuilt 1725. Weber carb from Sunbeam Specialties - about 10 years old, but also freshly rebuilt. Set carb according to Weber instructions - 1.5 turns in on speed screw and 2 turns out on mixture. Starts and runs poorly at about 500 rpms. Turn mixture in - no real change until 1 full turn in, where rpm increases a bit and idle improves. Turn in another 1/2 turn and rpm increases further with better idle. Turn mixture screw all the way in and have really smooth idle at about 1000 rpms (speed screw not touched). Also note: prior to carb rebuild on old worn out engine, the carb pretty much reacted the same way.
What do you guys think?
Thanks.
Mike
