that limited max power. If you can get your hands on a "slug"
piston, without all the weight saving machining done to the skirt, you would be
better off, but a lighter piston will be OK, it just won't last as long.
Of course, when changing out the piston, use a new piston ring. <br>

Subject: Re: [NSRCA-discussion] 120 AC issues UPDATE<br>
<br>
I want to thank everyone for their suggestions. Too many possibilities :)<br>
First thing I did was to change the liner and the exhaust. Replaced tank
internals. Decided to run it on the ground at home and save a trip to the
field.<br>
After 5 minutes or so flying issue was reproduced. Motor started surging
and would not go to full throttle from idle. Needle valve setting didn't
seem to matter. Switch to 30% heli fuel no difference.<br>
Changed both check valves no change. Took the motor out again swapped the
original liner back in and checked the regulator. <br>
-Bingo the edges of the silicone diaphragm are frayed. Replaced the
entire regulator unit with one from an un-run 120AC (thanks Norm S.) figured
that had to be the cause.<br>
No change still surging and no power after heating up. The motor still
turns free, no binding so although I will try a different piston and front
bearing I do not believe that to be the issue.<br>
APC 14x12 used for all of today's tests.<br>
I think I will put a well used but last time ran fine 120 in it and try to
diagnose this motor on the test stand.. I'll see if the same issue crops
up with a different motor.<br>
