I have been trying to get my 750 Seca out of moth balls for a couple months now and finally just fired it up the other day but it doesn't seem to be getting fuel on cylinder one. I have verified there is spark and even swapped plug, wire and plug cap from cylinder 4 to confirm the problem stays with cylinder one. Exhaust pipe doesn't get warm at idle or at 2000 to 3000 RPMS unless I shoot a little carb cleaner into the intake then it does but cools back off. I have confirmed there is fuel in the bowl and in fact just set the floats after rebuilding the carbs so the level is right. Not sure what I might be missing here that would affect both the idle and main circuits. Any suggestions would be welcome.
