Here is my test report.

I came to our local track to make test with thise setup / settings:

- Go 7 Port Turbo
- OS P3 plug
- 0.4 mm shimmed
- Jet's 25% nitro (10% oil)
- long needle carb
- 8.0 mm carb insert
- 0.7 mm idle gap
- HSN 1/2 turn in from flush
- LSN 2 1/2 turns in from flush

Conclusion

HSN was set too rich, so I leaned it down and came to optimal settings for my engine:
- HSN 1 1/4 to 1 1/2 turns in from flush

LSN setting was OK (i did the pinch test), maybe 1/4 of turn less:
- LSN 2 1/4 to 2 1/2 turns in from flush

Engine temp never reached more than 135°C (275°F).

It seems that those settings fits best for my engine. I only don't understand, why are my settings so different from other guys that own same engine.
But at the end, it realy doesn't matter, because I'm very satisfied with my engine performance.
