firstly i hope u put after run oil after you quit in January.
secondly do you know the Standard Needle Settings? If i stuff up my tune, i always go back to standard settings, which should be a rich setting and then you can gradually lean out from there.
finally if you cant get it starter yourself, its best to take it to your nearest track, when there is a club day on. most people there would be able to help you out.
anyway here is my diagnosis from what you say...
The only way to get it to run is to leave the GP Ignitor on then it will run horribly but it will run
you probably need
1. Hotter Plug - Vspec like P3 plugs
2. you are probably running on the rich side, try gradually leaning out the top by 1/4turns. (clockwise)
3. make sure the plug is on very very tight. turbo plugs need to be put on very hard to seal properly
