Hey Norm, I have not gone through as many PTs as you, and probably not as much as the others here. But I've had steel needles, black needles, yellow needles and pink needles. They all seem to work fine.
My troubles all seem to be with governing. I don't know why, must be air leaks somewhere, even though I've replaced the usual seals. Going to buy two full replacement carbies and see where I end up.
Did I read correctly that you add sump oil to the fuel to make your mix? I echo the others here. Reckon that might be causing issues for you.
I don't collect mowers. I just require Multiple Mowing Solutions™.
