Question
saw not idoling .  only start with full choke. new plug . now it won't start unles soak plug in petrol.           cheers trev.

Answer
Hi Trev,

It sounds like a lack of fuel flow to the engine.  Probably a dirty or gummed carb.  I would disassemble it and clean it.  Adding a carb rebuild kit wouldn't hurt either.  Check the in-tank fuel filter first.  Also, make sure the air filter and exhaust spark arrester screen are clean.

Good Luck,
Michael
