Hi Ric, I'm in the process of assembling a new GP 202 and am a little confused regarding some of the postings I've seen regarding right thrust and up-thrust. How and where do you establish the thrust line as a reference point. I've yet to see any plane of this type with up-thrust on the engine but mine appears to be about 1.5 degrees up and near 3 degrees right. What changes have you found necessary? Now would be a good time for me to make any necessary changes before I secure the cowl and space the spinner, etc.. Thanks for your time and interest. Terry
