Question about Saws
I need to service a stihl ts 420 concrete saw and dont know how?
replace the decompression valve. also check for carbon buildup on top of piston. usually when a saw stops on its own after 5 min or so.... the piston and jug are scored and need to be replaced.

You should go to a Stihl dealer and ask for the belt for a TS 400 Cut Off Saw. The belt is ribbed, you should only put on a Stihl part to replace the belt and make sure the belt is under the correct tension. When you go to the Stihl dealer you can ask them to show you how to make sure the belt is under the correct amount of tension.

the jets in the carburetor need to be cleaned out very well to operate this engine
the holes in the jets are very small and clog up easily with in a year or two
