sa what am I to do?? I do have a problem of this engine don't want to run at any thing below half throtle (acts like it wants to run but cant, I think we allready know why.) and I need idle to taxi. so should I just get me a extra engine mount from teh hobby shop and fashion me up a engine test stand?? that would be easier than trying to hold down a light easily breakable plane for the hours its gona take to make this engine into a broken in engine. mater of fact I think that will be todays project. take some wood and make an engine stand that I can clamp down to some thing and let run through a couple tanks of fuel.
