Spark plugs ??

[Tim Baxter]

Unscrew a spark plug, leave it connected resting on an earth (cylinder block etc) and look for spark.  If spark ok then look to fuel problem.  Put plug back, if it has carb pour petrol intelligently (maybe with syringe to avoid fire etc) directly into carb and see if it fires.  If it has injectors unscrew fuel supply to one and point (safely) into jar to see if fuel is delivered.  Buy a Haynes.  Good luck
