I've been in the hobby for not quite a year yet, and have bought 4 AX engines. I am absolutely amazed at the reliability, simplicity, fantastic service, etc.
I get the best feeling when I get to the field, prime my engine with like two prop flips, and the engine starts on the first flip with the stick.
The other day I had to change something around in my plane. I set the needles back to the starting point as suggested in the manual, and in half of (an external) 6oz fuel tank, I had the high end set, the low end set, and was having perfect transition on my 120AX. The engine barely has a gallon and a half of fuel through it, total, and runs like a dream.[8D]
I talk to them like they are my pets.[sm=bananahead.gif]
Too bad they don't make a 1.50 four stroke[&o] But then there's YS[sm=punching.gif]
