<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> Thanks for the suggestion. The pump was
completely disassembled last fall, when I was chasing a bigger issue (the
engine would not run at all). Turned out the carb had a defect (I think maybe
it had been dropped), and either did not seal properly any more, or distorted
the fuel flow somehow. We tracked it down by switching it out with another
carb, and discovering that the original could not be tightened onto the body
properly without jamming the barrel. I’ve also made the pump mods
recommended by Lance at Aeroslave, removing the plastic spacer on the pump back
plate.</span></font><font color=navy><span style='color:navy'><o:p></o:p></span></font></p>

it back on. The motor settled down after that.</span></font><o:p></o:p></p>

</span></font><font size=2 face=Arial><span style='font-size:10.0pt;font-family:
Arial'>I’ve been setting up a Mintor 1.70 in a new plane, and am running
into some minor difficulties. I first started running the engine last fall, and
has some mechanical trouble which lead to some major needle twisting. After
getting the mechanical trouble out of the way, I’ve found myself trying
to get the pump/needles back to where they should be, with varying levels of
success.</span></font><o:p></o:p></p>

Arial'>The</span></font> <font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>original symptoms seemed to indicate a lean mid-range on the
engine; dying on throttle up after a down line, the odd backfire when spooling
up from idle in the flat. I’ve been constantly richening the pump in an
attempt to solve these issues, and it seemed to work at first. Better
mid-range, no dead sticks. However, I am still getting the odd backfire, and
I’m really afraid that I’m going to start busting stuff.</span></font>
<font size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>I am
now well in on the pump screw, much further than another Mintor 1.70</span></font>

needle is also on the rich side of the setting.</span></font><o:p></o:p></p>

been checked, and they are fine (pretty much new anyway). The tank clunk is free,
and the vent line is clear. Is it possible the backfire issue is in fact a too
rich mixture, and I’m chasing the problem the wrong way?</span></font><o:p></o:p></p>
