Help!! I,ve been working on this 1980 txl 340 liquid cooled sled.when i picked it up it was running on 1 cyl.that was cool considering it was sitting in a bush for 10 plus years.so before blowing it up i changed seals and gaskets,overhauled the fuel pump,cleaned the carbs.got it going it was running on all cyl.and after a while running it ,it dropped the mag side cyl.so i checked for spark and there was but that plug was very faint compaired to the other.i swapped plug wires and carbs it didnt follow it was still that cyl. Any thoughts would be appreciated thanks.
