Good numbers, well done. Any idea what the hp was without the nitro shot ?
Regarding the jet sizes, my H12 runs a 108 main as standard. I just stripped the carbs off to see if they were gunged up as it will not idle reliably & had been laid up all winter. Carbs are clean, but the idle mixture screws were in odd places, one was 2-1/4 out & one was almost full in !? Someone must have messed about with it in the past !
Good luck with the final tuning & the run in April.
