Quick update, RT3-500 now 98% rebuilt and waiting to be fired up. Quite excited but apprehensive following a full nut and bolt rebuild. One question I hope someone may be able to answer is regarding fuel. I've heard that the Novamotor can use Sunoco 105, but that also people have used a mixture of Avgas and other additives. Can anyone let me know what the exact blend should be? Also, there seems to be difficulty in pressing my throttle pedal in that the whole slide throttle assembly is rebuilt and very smooth but once coupled to the fuel pump and including the friction in the cable to the pedal etc. it all adds up to a particularly firm / slow responding pedal feel. Obviously I need to try and improve the action, but am wondering whether the lack of use has 'gluped' up the remaining fuel in the cam driven pump and made it sticky? I'm wondering whether running it up will in turn improve the whole throttle assembly. Has anyone else come accross this?
