About the Stihl TS400 Cutquik Cut-Off Saw
The Stihl TS400 Cutquik concrete cut-off saw is one of the most popular saw models used by concrete contractors, landscapers, foundation contractors and others. The TS400 has a reputation worldwide for being one of the most dependable and better performing saws among cut-off saws.
There are many features the Stihl TS400 is known for, but cutting performance is number one. Also known for exceptionally long running times and a decrease in service intervals, the TS400 provides outstanding performance compared to other cut-off saws.

Before purchasing a carburetor for your Stihl TS400, it’s important to identify the carburetor from your cut-off saw.

About Stihl TS400 Ignition Coils
If your TS400 is running poorly, or missing, the ignition coil module may need to be replaced. There are two types of ignition coils for the TS400 cut-off saw. There is an older style 3 bolt ignition coil (4223-400-1300), which can be identified by the 3 bolt flywheel (4223-400-1200), and a newer style 2 bolt ignition coil (4223-400-1303), which can be identified by the 2 bolt flywheel (4223-400-1201). 3 bolt and 2 bolt ignition coils are not interchangeable, so make sure you identify the correct coil before ordering ignition parts for your TS400.
