What fuel mix are you using and what intake did you put on?
I use the Victa Formula-V in all 2-stroke Victa's, mixed at 25:1. For all other 2-stokes, I used the Stihl HP Ultra Synthetic because it significantly reduces carbon.

The intake I used was the long type with the filter-less restrictor, mainly as an interim until I get the original short pod style one sorted.

I've since pulled the plug again to check for spark and found the original plug has virtually no electrode left. I'm still waiting for a new plug to arrive, but I hooked the plug wire to another brand new plug I had in stock and it was producing nice blue spark. So yeah, new plug most certainly needed.
