Yes but I had changed a couple of things. I had been having flame outs while advancing the throttle from mid to WOT and today I got the low end about as lean as I could get it without it dying but I was having lots of trouble with the Merlin HD2003 (long reach heavy duty hot plug) plug I had put in it. the 60NX did not like this plug - AT ALL. My first hint was when it started to run in a way I have never seen a plane motor "run" before. I start this engine with a chicken stick and after I primed it, closed the throttle to just above idle, I flipped it once. It hit, bounced off the compression stroke and went backwards, bounced off the compression stroke and went forward and it stayed "running" like this for a good 50-60 iterations as I looked on in bewilderment. So I guess it was a 1.5 stroke engine at that time. I flipped it again and it hit hard against the stick. Another flip and it started backwards and as I closed the throttle it started running forward nicely but as soon as I took the glow starter off it died. Started it again and ran it up and it stayed running but obviously didn't like the plug. I stopped it and put in a Merlin HD2002 (long reach medium heavy duty) and the motor was transformed. Very snappy response with no mid range sag during throttle advance. With a 10x8, this motor has near instant throttle response any way before and after the mods but I was digging the way this thing was running. I just love this engine. The stock muffler is absolute, 100% garbage so you have to spend the extra cash to get a better exhaust but with a Macs pipe or the EVO/Jett muffler it is a hoss. Not bad for the $124 I paid for it. I'll get another one soon to put it on a little Rookie club racer I have a 46AX on currently.

By the way, I was running 15% Omega Aero with 18% castor/syn oil.


Thanks again. Your wisdom is much appreciated but why convert it when you can just buy one here - The new Magnum Gas XLS-52.
