RE: Setting up an OS 1.60, cline, bisson pitts, 18x6w
I wouldn't waste the money on the 18x8w, try a standard 18x8.
The engine is just a hobby/sports engine thats works fine on 0-5%. Th fact that is so realiable & friendly has lead to it being used sucessfully on the F3A circuit.
Shimming is typical for several engines, OS 1.40RX for example. Thrust me, we're not talking loosing power here , thats not the plan it's just to soft the very top end which will be over hard because of the 15%. Try it they're so much smoother. The plug. The f type if just the alround pro plug.
15%- 1 shim- F plug. It's a great setup.
What I'm not sure about is the Cline on that engine.
