RE: Norvel .15 tuning?
Hi!
If you have tried 25% nitro earlier and it now runs better with 10%...why not try 5%nitro?!
...or just richen the needle somewhat.
But most important is...How does the engine sound and react now compared to when you ran 25% nitro earlier...??? Is it easier to needle it now or...???
Regards!
