Fuel and Glow Plug recommendations
 

I bought an older On-road RC that came with a Novarossi 35 Plus 21 LC/WC09 Limited edition engine and cannot find a manual for it and I need to find out what fuel and glow plug I should use in the engine. I have been doing research, but the most I can find out is that it may have come with a C7TGF glow plug, but am not sure of the reliability of that information. I am not looking to max out performance, in fact wouldn't mind a detune while I learn to handle this beast. Any suggestions would be helpful. Thanks

The Novarossi plugs become harder to find, the OS RP7 is the most used plug today, it is like a Novarossi 8 which is perfect for a 35+

Thanks!
