Hi

I have the Novarossi RR12L5 long stroke engine fitted to an Fw-05 with JPL 6mm pipe.

I'm running 16% Nitro and a No 5 Novarossi plug. The head clearance is 0.018" (It has a 0.3mm shim in)

The engine doesnt seem to have any top end power. I have toi use the lowest top end gear to get it to rev out. If i use a taller gear it doesnt get to top speed.

I need about a 15% increase in power. Anybody have any idea what could be the problem? Motorman?


Cheers
