<div>John</div> <div> </div> <div>My 6 year old rx ran at 3/4 turns out from new usign a Bolly muffler. When I went to a tuned pipe it was exactly as you described. I tried all sorts of combinations of idle, pump settings and header lenghts and never found a combination I liked. </div> <div> </div> <div>The whitness stripe on the pump should confirm that the pump was moved.</div> <div> </div> <div>Colin<BR><BR><B><I>John Pavlick <jpavlick@idseng.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">I'm having some trouble with my OS 140Rx and it seems to me that maybe<BR>somebody played with the pump (I bought this motor used). Here's what's<BR>going on. The main needle wants to be at about 3/4 turns out. Not even a<BR>full turn. If I open it to 1 1/4 turns it's slobbering rich. The idle is<BR>rich even with the adjustment turned fully clockwise. It is flyable, but
I<BR>know something isn't right. This motor also has a dual-plug OS head. I have<BR>an "F" plug in the center and an "8" in the rear. The transition isn't<BR>great, especially at about 1/2 throttle. On the ground it will actually load<BR>up sometimes. In the air it's not so bad but it doesn't sound right. If it<BR>had a Perry pump I'd back off the pressure and that would probably fix it.<BR>Like I said, I'm thinking someone played with the pump for whatever reason.<BR>Is there any way to set it up as it was originally or do I have to send it<BR>back to the service center?<BR><BR>John Pavlick<BR>http://www.idseng.com<BR><BR>--<BR>No virus found in this outgoing message.<BR>Checked by AVG Free Edition.<BR>Version: 7.1.405 / Virus Database: 268.12.8/455 - Release Date: 9/22/06<BR><BR>_______________________________________________<BR>NSRCA-discussion mailing
