Update:

So new plug , the working when last run carb set to standard
and will not start still. Sparks and fuel getting to plug.
It will not fire at all . Spits once maybe after 1st pull then
20 more nothing.  Clean up plug , then same again.

- NOT tried new fuel
- NOT tried new fuel hoses
- just piston ring - I'll log that but that is a last resort .

I will try new fuel a d then I'll buy a carb with bits off net
But with fuel lines.

If that don't work then it's scrap but I might saw the engine in half
To see if piston ring bust.

What damned annoyingly poor engines to work on

Have you replaced the fuel filter? they may look okay but they clog up and starve the carb under load

Next time on the strimmer I will.

Do the new fuel and check the fuel filter which seems
to be in the fuel tank.
Next contract I buy a new carb (I know they are cheap but
I refuse to ware money on this thing)

If that don't work then I give up.
I'll report ...
