Hi.

Im new here and i am in need of some help!!

I come to start my petrol strimmer today and it starts but it struggles
to tick over. it splutters and coughs trying its hardest to stay alive
but then sadly dies. I took the spark plug out and noticed some black
grainy residue on the bottom and it seems to be all over the piston, is
this doomed or can i save it from the scrap heap its only 14-15 month
old!!

It's my fault i left the petrol in it while storing it maybe thats the
cause i dont know.

Oh its a 33cc spear and jackson brush cutter from argos.

any help truly appreciated thanks
andy.


Sounds to me like it has been stored too long with fuel in tank. Petrol
evaporates and leaves a high oil content which will block fuel lines.
Drain off whatever residue you can from the fuel tank.
Add some 50/1 mix and give it a hard workout. This should clear oil residue
from the innards.
Don't use ordinary car engine oil for the mix.

As an apprentice I was told to NEVER use a wire brush on a spark plug as
this can damage the ceramic coating.
Use a fine abrasive paper or tape to clean the contacts. Then reset the gap.
Always worked for me.
Mind you, spark plug technology may have changed in the last 40 years.
I think it good practice nevertheless.
Don't run a 2 stroke on neat petrol unless you have some intention of saying
goodbye.

Good luck
Francis
