I ran into a dandy this time. My friend's Stihl FS 46 engine will not start. In fact, it won't even pop, either on choke or otherwise.
(1) Tried a new carb. Still no pop.
(2) Checked for a spark. It's there.
(3) Plug is new, but I tried another anyway. Still no pop.
(4) Checked fuel lines and replaced fuel filter. Still no pop.
(5) Checked rings and compression. Rings are good and compression is at 130 psi.
(6) Checked for muffler blockage. None exists.
This engine should be running, unless it's a timing issue (spark fires at the wrong point). The spark is damp when removed, so that's my last hope. Is there any way that I can easily check that spark ignition firing? Or, is it possible something else is wrong? I'm at the end of the rope. TIA.
