Subject: Re: [NSRCA-discussion] 120 AC issues UPDATE<br>
<br>
I want to thank everyone for their suggestions.&nbsp; Too many possibilities :)<br>
First thing I did was to change the liner and the exhaust.&nbsp; Replaced tank
internals.&nbsp; 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.&nbsp; Motor started surging
and would not go to full throttle from idle.&nbsp; Needle valve setting didn't
seem to matter.&nbsp; Switch to 30% heli fuel no difference.<br>
Changed both check valves no change.&nbsp; Took the motor out again swapped the
original liner back in and checked the regulator.&nbsp; <br>
-Bingo the edges of the silicone diaphragm are frayed.&nbsp; 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.&nbsp; 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..&nbsp; I'll see if the same issue crops
up with a different motor.<br>
