Assumng you mean the electronic coil pack when you say "stator", they are a known weak point, so that probably is the problem. It depends what engie is fitted - if it's a Tecumseh, the coil is mounted outside the flywheel. If this is the case, I have them in stock new or used (£10 and £25 respectively). If it's the older engine with the coil under the flywheel, good luck. These consign more machines to the tip than anything else.
Before condemning it, check that the stop switch (on the speed control assembly) hasn't grounded out.
