About this part

The TS410 and TS420 are the cut-off saws on nearly every concrete crew, and they live in dust. This kit replaces the C1Q-S118 carburetor and adds the air filter, pre-filter, primer pump, fuel filter and plug.

Always fit the new filters with the new carb. A clogged filter on a cut-off saw will kill a fresh carburetor fast.
