Thanks for the Reply, that is exactly what I did with my 3W55, 2.5 gal of premium with lawnboy and now 50:1 with Dominator synth. That eng pulls my 21lb Python Pitts around like a .40 size ship that is over powerd.

I will be putting this eng in a Sig Rascal 110 and will be running the Xoar 18X6 on it.

I want to give this eng a work out as it may be going in a H9 P47 150 next but want to run it in the Rascal first for a while.
