G'day vint_mow,
I am having the same issue at present with a Victa Mayfair Deluxe I bought off gumtree. The previous owner said it was running in the past but had stopped. I found it had plenty of spark. So I cleaned the plug and got fuel going through the tickler. After a few false starts I got it to run. Sometimes it will idle back, but most times it just takes off like a jet and keeps over-revving even when the control lever is pushed to "Slow" position. If you take it down any further it just stops.
If it has the G3 carby, I'd check that the governor gears are OK. Pull off the cowlings, and check that the plastic flag will rotate back and forth about 30�. If it will move further, the gears are stripped and must be replaced.
Also can anyone please tell me, what is the correct spark plug for the Victa Mayfair, and what is the correct gap for plug and points? I am using a 25:1 fuel/oil ratio plus a bit extra oil to accommodate for the age and wear. The engine does not smoke at all, which I take as a good sign(?). I recall a relative had one of these and it smoked worse than an old steam train. After mowing the lawn your clothes smelled like you had just been fighting a bushfire.
25:1 will be just fine, with modern 2-stroke oils.
Plug gap is 0.025"; points gap is 0.020" if the coil is under the flywheel, 0.027" if the coil is external.
There are a couple of possibilities for the spark plug type; we really need some pics to determine the exact model you have. Might be best to start a new thread!
