size=2>A big problem I am having is it wont go to full throttle. At about
1/3 throttle or less it goes lean and stops. How can this be rich. I tried
this approach even at 1 1/2 turns out on main needle with the same
results. What about the loud metal rattle that is coming from the pump
assembly.</FONT></SPAN></DIV>

<DIV><FONT size=2>Peter,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>It sounds like your running the engine way too
rich. When I got my first DZ, I set it up the same way, and had
the same problem. You cannot run it like an "L". If you have
adjusted the pump from the factory setting......return it to it's
original position and start with the high speed needle at 1 1/8 to 1 1/4
turns out from full closed. If the motor starts.....let it warm up
a minute then advance it to full throttle. Once at full throttle,
<STRONG><U>slowly</U></STRONG> (one or two clicks at a time) turn
the needle in to lean it until the RPM drops. Once you hear the
RPM start to drop, richen it back three or so clicks and run it. I
know what your thinking...."It sounds way to lean" but this is how
Richard from YS Performance told me to set it up, and I've had no
problems with this. Once the motor is broke in the high speed
needle should be around 3/4 to 1 turn out from full close. Hope
this helps.</FONT></DIV>
