Thanks for following up. Lots of folks never do.
The timing fix is easy and essential.
Is your compression really 9.2? Was it checked? Even if it is, that's not much.
Don't give in to N2o or more mods until you get what you have right.

Absolutely! Want to make sure everything is sorted before I do anything else.

Pistons are down the bores around 70-80 thou, flat tops and 84cc heads milled down 50 thou. So I reckon it would be roughly around that.
