I have a Victa Lawnmaster Quattro 40 and it has developed a problem - hopefully someone can assist.
1. When cold it takes 20-30 pushes to prime fuel unless the fuel tank is full and it primes almost immediately.
2. It tends to race (fast then slow)
3. When the tank is half full it stops.
Lately the fast /slow racing is more pronounced and after a couple of mins it just stops altogether.
I have changed the spark plug and fuel.
Fuel is correct mix.
Fuel flow is OK
