<DIV><FONT face=Arial size=2>The engine is a 140.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have had the engine about a year. The pipe is one
piece 5 oz. The header was included so I thought they would match. I
didn't mess with the pump as I "adjusted" the pump on one of the first Hano 61's
and never did get it readjusted. Had to send it back to the sevice center and
they set it back in.</FONT></DIV>
<DIV><FONT face=Arial size=2>Is counter clockwise lower pressure on the
pump screw?</FONT></DIV>
<DIV><FONT face=Arial size=2>Thanks for the advice and insight. </FONT></DIV>

<DIV><FONT face=Arial size=2>Bob,</FONT></DIV>
<DIV><FONT face=Arial size=2>You say you are running the 140? or is it
the 170? Which Mintor aluminum pipe, the sectional one at 3.5 oz or the
old style at 5 oz? They have different baffle positions and the tuning
lengths are different. Mintor began supplying a different length header
when they released the new lighter pipe, so there's a possibility you have a
mismatch. I'm very familiar with the 170 but less so with the 140, in as much
as they have exchangeable parts. </FONT></DIV>
<DIV><FONT face=Arial size=2> You want to prop the engine to run about
8000-8200, so the advice of others to use more prop is good. If you want
some more details visit my website at <A
href="http://www.aeroslave.com">www.aeroslave.com</A> under 3m Mintor engine
tips and tricks. I have some advice there. You probably will have
to lower the pump pressure 1/2 turn because I did when testing the engine with
CoolPower. Feel free to contact me off list with more details and I'm
sure we can resolve this. When set up right the Mintor (170 at least)
has the most linear 2 stroke carb out there. </FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> Mentor 140 Problem</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I need advice. I have been trying to dial
in a Mentor 140 for 6 or 7 months. I have about 7 or 8 gallons of fuel thru
it. It took forever to get it to run half way right but it finally started
to work. I have it in a test plane because I still don't trust it. After
break-in I tried to fly it but it would surge at any low power setting.
The people I got it from sent me a new pump and carb. It will now idle well
but mid-rang is so rich it will 4 stroke. I was told to lengthen the pipe,
which I did. It was set at 1/2 in. between the header and front of
the pipe. By the way the pipe is the aluminum pipe from Mentor. The header
is a 30mm. rise from Mentor. </FONT></DIV>
<DIV><FONT face=Arial size=2>I leaned the low end and set the pipe at 3/4
in. spacing. I also leaned the top end. I have tried lean and rich on both
top and bottom. It always runs very rich mid-range. I am using 15 % Cool
Power. 17x8N APC. RPM top is 8800. I richened it to 8400, 8500, 8600. Idle
is very good and reliable. When I pull verticle, that is when it leans
out and runs like it should, however blowing the top of the box at 80 mph
ain't cool. </FONT> </DIV>
<DIV><FONT face=Arial size=2>I was told to lower the pump pressure, which I
have not done yet. </FONT></DIV>
<DIV><FONT face=Arial size=2>I have run YS,OS,Supertiger, Hano's for 15
years, but this is the most flustrating thing I have ever
seen.</FONT></DIV>
<DIV><FONT face=Arial size=2>The power is scary, however I would like to
have throttle control instead if a "parked and gone"
switch. </FONT></DIV>
<DIV><FONT face=Arial size=2>HELP</FONT></DIV>
