Ray - you need to go thru learning curve on this setup-
th best fuel mix we found was 20% Klotz and 5% nitro.
prop - 18x8 IF a decent tuned system is used = 8000rpm -9000rpm.
The muffler used can kill the project
Why?

the st2300 carb is difficult to set for best idle /transfer in mid range -to full power --unless you have 1/2-3/4 psi on the tank as the engine reaches the last 1000 rpm.
You may havesome success with a pump or a regulator (demand type -
The ignition setup can produce a beautiful smooth running setup -with better power than allowing the glow plug to set the timing
It can also mask lean fuel runs and cause you to wreck the engine -
It is a learning curve -be patient -
