Hobbsy / DieselDan
I am using 12x8 or 13x6 at both prop I never get over 8100 rpm. Most the time only 7500rpm
I blend the fuel as Davis wrote me (I try to made some minor changes) I use 1.5% MEKP
I adjust the main needle for max rpm and then the the press. screw to get max rpm
and go again to the main needle I repeat this until I get the max rpm in both.
I have the "Dr Diesel" booklet.

Do you have any idea to get better?

Thanks
Barkai
