I fitted a Perry carburetor on my 160FX and I have impressive power, swinging a 18X6 masterairscrew @ 9400 rpm on rich side of the screw.

I made many experimentation. I have run this engine with OS muffler, and with Pitts Muffler and Cline Regulator, all with no good results. Lean running in middle range , overheating and dead stick power.

Now, with Perry Carburetor, Pitts Muffler and Cline regulator, the 160 run very strong and lean dead stick conditions are completely end.

Very strong impressive engine.

Sorry for my English.
