Bill,<br /><br />Yes you should worry about the link & sync, but not necessarily after a carburettor overhaul (if that is what you mean) because my personal opinion is (don't take it for granted, I'm not a specialist) that a carb overhaul would not mess up the initial settings that much. The question is if the link & sync was ok before the carb overhaul, if not it needs to be adjusted. But in order to get a good running engine all the settings need to be ok, like max. ignition advance, ignition timing @ idle, link & sync of carbs & ignition, sync of the 2 carbs to each other, max. opening of throttle butterflies and other things like compression, carbon build-up may have an effect on how it runs.<br /><br />You don't need to replace all internal parts of the carburettors, but only those who are provided in a rebuild kit (like float, float needle, float needle seating etc..) don't forget to adjust the float setting also (follow your manual).<br /><br />Although it sounds logical to me that it is a fuel delivery problem, you must not overlook the basic troubleshooting steps: compression ok? (compression test) spark ok? (spark test) fuel delivery ok? (check spark plug color, spray premixed fuel in carb throat while running) Do a search for these basic tests over here about the details.
