A 70 should be a cracking engine.
 
My mate has one that he tried to fly on the recommended 52FS, and whilst it would just about fly, he thought it was very underpowered (it should be borne in mind that his throttle is more like an on/off switch though!).
 
I think it might have been a 70FS he went up to.

Hi guys
 
Does anyone have any suggestions for the best way to extend the fuel needle control through the large cowl of the Gilmore racer. It must be sufficiently long to turn by hand when the engine is running but short enough  or flexible to allow the cowl to be manoeuvred into position.
 
regards Hans

Solid wire extensions to needle valves are often the cause of poor running due to the extra vibration transmitted back to the delicate tolerances of the needle assembly.
The recommended system is to use something like a piece of fuel tubing over the end of the original needle, and then use this as a guide to insert a small screwdriver / allen key whatever into the end of the needle and adjust.
