Stihl 420 cement saw changed out coil still no spark???

SOURCE: Chain Saw, Stihl Model 011, cutting off

I've been messin with my poulan 2150 that was doing the same thing. Good, fresh gas, good spark,etc. I noticed whenever I loosened the fuel cap it would literally spray gas out! alas, I removed the muiffler assy and the darn thing fired up the first pull! I've got the muffler parts soaking in gas right now and I'm sure this the problem. It just makes sense especially if you use the same 'mixed fuel' can for weed eater, blower,etc. Check your's out, it could very well be your problem too! GOOD LUCK

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode.

Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when flywheel is rotated.

SOURCE: hi there; my stihl ts 420 does not start easily

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.
