<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff> When I
got my first 120ac I ran it for awhile not realizing it was sick till I went to
a contest when an experienced 4 cycle modeler said my engine sounded sick. Asked
why he thought that and he could tell with his ear that it had a funny noise, I
have hearing lose from NAM, and we pulled valve cover. He adjusted valves and
found it was off and inconsistent in rpm runs at high. Discovered it had a
missing E clip and never found the pieces. Engine was bought used and fresh
rebuild. I had toast for rocker, pushrod was a mushroom. After repairs it ran
the way it should have right along. Did it break or was it missing from the
rebuild. No overt sign of internal scoring or where the pieces may have gone if
their was one. </FONT></STRONG></DIV>
<DIV><STRONG><FONT face="MS Sans Serif" color=#0000ff> One of
reasons I hate 4 cycles. Unless I dump those planes that are set up for fours I
have to put up with them.</FONT></STRONG></DIV>

<DIV><BR></DIV>Good News...Found the problem...<BR><BR>Bad News...Unless
someone has parts and can bring them to the Lenox Contest, <BR>I will not be
flying the Focus and must live with the Aresti 40 once more...<BR><BR>The
problem was the E-Clip that holds the rocker arms on the shaft. The
<BR>exhaust side broke in about three pieces. One piece was jammed into the
<BR>valve cover holding the exhaust valve open...Walla, no compression. Engine
<BR>quit. Had compression as soon as I took the valve cover off. Took me a 1/2
<BR>hour to find all the pieces. Piston and everything else looks
good.<BR><BR>Part needed is YS0580, E-Clip Set. I will buy them off of anyone
that can <BR>bring it to the D4 Lenox contest. If not, There is a hobby shop
about 1-1/2 <BR>hours away...In the wrong direction for the
contest...<BR><BR>Has anybody else had this happen, or am I the only one with
a gremlin <BR>disassembling the engine from the inside?<BR><BR>See

don't think the low nitro would cause a "sudden" change or cause the
<BR>engine to quit as you say it did, but I agree with Eric that the YS's
enjoy <BR>Nitro.<BR><BR>Another thing to check if you've only run 10 flights
is the valves. I've <BR>had new or rebuilt engines where the valves have
tightened up after the <BR>first few flights and it caused sudden
failure. I like to set the <BR>clearences on the tight side, but if
they're tooooo tight, bad things happen <BR>:)<BR><BR><BR>-----Original

Help<BR><BR><BR>Larry<BR> Make sure the clunk is not in the front of the
tank. It is not Folded <BR>backwards. Check the plug and make sure low end
idle is set correct. Also <BR>maybe lean it some more so that the top end
won't be so loaded with fuel <BR>that it puts plug out when you pull it back
to idle. Sometimes My 140's will <BR>quit if I jerk them back to idle, if the
are too rich on top end. I know <BR>guys my low end may not be right
either.<BR><BR>just tho'ts<BR>Jim Ivey<BR><BR>----- Original Message

Help<BR><BR>I have a 140L in a Focus. Has been flying very well and very
strong, with <BR>never a problem. I have about 10 flights on this barely used
engine and I <BR>flame out in a very uncomfortable attitude. Vertical climb
flamed out at <BR>about 25% of the vertical in a stall turn. I was settled at
3/4 throttle, <BR>never need full throttle flying Sportsman with this
plane.<BR><BR>Although at the down wind part of the field and pointed the
wrong direction <BR>when the engine quit (straight up), I was able to drag her
all the way in <BR>and still managed to make it a very hot landing
<vbg>.<BR><BR>Anyway, What kind of things would cause a very strong
running motor to just <BR>quit? If anything it was a tad bit to the rich side
with a exhaust trail.<BR><BR>Fuel is WildCat 15% Nitro 18% Synth (no
castor).<BR><BR>Pretty vague question I know, just curious what this typically
ends up <BR>being. I was planning on taking it to a contest this
weekend.<BR><BR>See
