<DIV><FONT size=2>From new out of the box. Open the cam gear cover and put a
couple drops of oil in there. This will ensure that the cam has lube on the
first run. Don't use too much or too thick of an oil as it will be difficult to
start. You just want to have a little lube so its not dry. My latest engine was
good on the lube for the Cam out of the box. Just check it...The 170's have not
been sitting around too long.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Start it up, in the model no cowl on so you can see stuff and
it and it won't be bangin into the cowling.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Run it at 4000rpm this is a "high Idle" for about 1-2 tanks of
fuel...</FONT></DIV>
<DIV><FONT size=2>Don't worry to much about tweaking needle valves or
anything...just try to run it only at 4000rpm</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I do this in 4-5 minute segments at a time. Let it cool
completely in between. It usually will be about 3-4 sessions on a full 20oz
tank. This can be done on the model, just leave the cowl off so it doesn't
bounce into it.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Then after you have about (3-4) 5min runs at 4000rpm...you
can Set the top end and start to dial it in....It will be pretty
easy.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The 17-12 is a good prop for a light load and good power. Its
gets loud at the rpm the 170 will pull it.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>The 17-12W is a good option as are the 16.5-13W and some of
the 18.1's. Another really excellent prop is the 17-13. Very good and good on
sound as well.</FONT></DIV>

in Procedure</DIV>
<DIV><BR></DIV>
<DIV>Hi all</DIV>
<DIV> </DIV>
<DIV>The weather is finally good enough to start flying in Ontario so I would
like to fire up the YS. It's been a while since last I ran one and would
prefer not to screw up the nice new motor.</DIV>
<DIV> </DIV>
<DIV>I'm running the Hatori muffler/header and the engine in mounted using a
Hyde 170ARA. Of course I'll use 30% Heli fuel, 16.5 to 17-12 APC and a "soft
start" glow igniter.</DIV>
<DIV> </DIV>
<DIV>Any advice on the best way to run-in these things? Should I run it in
while mounted in the plane, or would that be too much for airframe?</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
<DIV>Colin.</DIV>
