well crap, my head just exploded !!

Chad Veich, I hear you, but, I was just using my Zenoah as an example of weight, if I did use it I would have to cut a 2&1/2 inch hole on one side of the Cowl for the Carb, and a much-much larger hole on the other side for the muffler, besides, to do some "preliminary testing" I would have to drill holes in the Engine Wall that I may not even use,,

for something different I wanted to buy the HP 120 Inline Twin 2st, with mufflers it should come in around the same weight as my Zenoah 20, but it will cost $600 with mufflers to get it in the plane, I'm frustrated, I can't even find a set of reliable Rotating Electric Retracts for it under $400

but as they say,,,,, "That's the Hobby"
