gGys i recently picked up a 40 size u-can-do and let me tell you its great but what im having a problem with is the cowling being parallel to the backplate of the spinner. I mounted the 0.S. 70 per instructions but when i look (from the side at the front of the cowling around the prop shaft its not parallel to the backplate of the spinner its a real eye sore. I had thought about loosing the upper mount bolts until it lowered the engine enough and then put washers behind the upper two mounting bolts to compensate (maybe 1/8th inch most is what im needing) to put the two parellel to each other. my question is this if i lower the mount will it hurt the plane at all by doing so like make it fly bad or wrong or should i just accept that the cowling isnt perfectly parallel to the backplate any suggestions would be greatly appreciated oh and by lower the mount i mean basically pivot the mount by the two bottom screws to bring the front of the engine down some
