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>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>
