Hello all,

Recently I converted a Ryobi 31cc using WackerEngine parts and now Im at the point where Im about to mount it to my plane, a Cap 231EX. Now, this is my first gas engine and I have a few questions on how I go about setting up the tank and tuning it. I know this topice probably would have been better suited in the general gas forum, but because this IS an converted engine, I know a few of you would probably be more helpful here.

So my first question is how do I set up the entire fuel system? I have the tank that came with the plane, besides replacing the fuel lines to gas lines, will this tank work our should I replace it completely (it was suggested that a 1.20-1.50 glow engine be fitted for this plane)? Which nipples on the Carb. go to which line and where do those lines go? Ive read about "looping" the fuel line, but how exactially do I do that?

Also, about tuning the engine, how exactially do the high and low speed needle valves need to be adjusted? I know from glow experience that you adjust the low speed untill it hesitates or dies on throttle up, then open in a bit from there, is this the same with gas? I know Ive seen suggestions that the plug be replaced and I currently have the "stock" plug in right now, which one should I switch it out with?

Thanks in advance for the help! After I recieve answers, Ill try and set it up and take pictures to let you all see if Im doing it right, or horribly wrong...
