Stihl FS56RC won’t fire.

[InspectorVol]

Replaced coil, new plug. Both check good with ohm meter.
It’s about 4 or 5 yrs old.
I’m at a loss.

First take off the muffler and take a peek.

Coil on backwards, if possible for your machine?

Get a cheap inline spark tester.

Did you get your parts off escam or cramazon? OEM Stilts?

You can only check the coil with an Ω meter if it has points or a remote trigger unit
The act of testing with some cheap meters can itself destroy the Hall effect trigger chip embedded in the coil.
coils either work or they don't work because they are not repairable
So you take the kill wire off the coil and check for a spark
No spark = dead coil or wrong coil

These newer coils put out a very faint spark.
