I have an older Yardsman riding lawn mower. It is back firing? I seems to be running very rich and idles up and down? It is an twin cylinder Brigs. Does the carb need adjusting? Thanks.

Post your Model,Type and Code numbers off the engine so we can tell which engine you have and to better diagnose your problem.

Depending on how old, there may not be any carb adjustments that can really be made. we really need the model number off the engine. or at least descride the engine and carb in great detail.
