Good morning BB and all
First let me make something very clear, possibly even clearer than Willie Rioli's sample. I have nothing but respect and thanks for all the good folk on here like your good self who give large amounts of their time at no cost to help others.
I thought it would be beneficial to the give the new member for both now and in the future the base line for simple process of elimination fault diagnosis. It's a pretty simple set of steps that only takes a minute or 2 and is designed to save time and money and quickly set you on the right track. Almost all owner manuals, workshop manuals etc have the same things in the trouble shooting section for if your mower won't start. I just think starting at step 1 not 4 or 5 is logical.
A quick example, was mowing the lawn a few months back, engine cut out, wheel mower to shed, check for fuel, yes, check spark, nil, get new plug out, don't install check for spark first, all good and mowing again in a few minutes. Being a Victa 2 stroke there was a thought of a stuck float needle but fortunately that was step 3.
Anyway, back on topic, I hope the advice from all Damian has received get's the engine to fire and then running nicely again. I hope is it the diaphragm, it's quicker than getting at the main jet. The engine pictured above was firing but not starting. It was a combination of bad fuel, hardened diaphragm, main jet and pick up filter screen blockages.
Cheers
