On breaking in of this engine, it was running "rough" say the least. First of all, it would hardly get to full throttle without dying, and when it finally did, it would "pulse" like you were workin' the throttle, only I wasn't, also it made a "mechanical" noise that didn't sound so good................Guess what?.........after reading some info you and others posted on the mighty 63, I replaced the tank, lines, and filter, added a couple oz. of klotz syn. 2-stroke oil to my gallon of 15% cool power, it now runs like a scared cat-burgular................conlclusion >>>>>>>>> this engine; #1, likes not to have ANY leaks in the fuel system (it was holding SOME
pressure, because when I'd go to refuel, it made that "sound") #2, it likes it's lube!!!!!...................My ?, Dave, is this; I'm going to order me some fuel for the year, 1st of March (LHS places a HUGE annual order, and we all save$$$$$) I was planning on getting either wildcat ys 20/20 , or wildcat 30% heli, or a combination of both, depending on $$$..........I'm into "fun-fly" type flying/manuvers, so power/throttle response is important.....How do these two fuels compare, and does the heli fuel need any oil added? I might consider getting another fuel, depending on price, but the two brands LHS is ordering, are morgan and wildcat, I think? (morgan cool power heli, or pattern?)

Either fuel is fine as is. I like 30% but it's hard on the wallet! Enjoy the 63, it's a great little engine.

Thanks Dave, I will. It's great to have you and so many fellow modelers at my fingertips for advice! Again. THANKS.
