<DIV>Larry, I have been running 140L's now for three years and have found the 15.5 X 13N and 15.5 X 13 works on the Finesse and Angels Shadows. I will get a solid 8500 static. The idle thing sounds like it has a problem getting down to 2K so the idle can be effective. It may be loading up too much with you trying to keep the top end R'sss down by richening. Once you get into the 8,400 to 8,600 RPM static range and only back off 2 to 3 clicks I bet the low end will clean up allowing you to get on the idle side of the carb. Then see what happens. I chased this same thing for half a season till Charlie Williams helped me out by getting the right prop and mixture combo</DIV>

<DIV>Jim Ivey was on target with his response, Sorry I wasn't clear, Hear is what I was looking for...</DIV>
<DIV> </DIV>
<DIV>What is the best Prop for this set up to get the optimum RPM range? I didn't think that the YS series liked to turn that high of RPM. What is optimum best RPM range for this engine</DIV>
<DIV> </DIV>
<DIV>The second question that Jim provided a response to was the idle, with spitting and not coming back down to the idle RPM causing a very hot landing if not prepared for it...</DIV>

<DIV>Thanks,</DIV>

<DIV><BR></DIV>
<DIV>OK...I've posted questions about problems in the past...Now this may be on the other end of the scale...</DIV>
<DIV> </DIV>
<DIV>My YS 140L was very strong this weekend. I have changed fuels and I'm using PowerMaster 30%-DZ.</DIV>
<DIV> </DIV>
<DIV>I know I'm turning too many RPMs so here is what I'm currently running:</DIV>
<DIV> </DIV>
<DIV>1) Prop 16x11 (Prop Clearance issue for anything bigger than a 16" dia)</DIV>
<DIV>2) Hatori Pipe...Has the tab for mounting built into the pipe. Don't remember the number.</DIV>
<DIV>3) 1/2" Header (Black and Tony Stillman thought it may be the header from Australia).</DIV>
<DIV>4) 1/2" Teflon coupler from McMasters.</DIV>
<DIV> </DIV>
<DIV>Sorry I don't have the numbers for the pipe and header, but I'm new and don't remember this stuff. I bought the plane used last year.</DIV>
<DIV> </DIV>
<DIV>Current max RPM is 9,200. I richened it up for 8,900 max. It does seem to spit allot at idle, but hold good pressure in the tank. I have programmed the idle up function on my Airtronics Stylus to drop about 500rpm for landing as it only comes back down to about 2700 - 2900 after running for a couple of minutes. Will idle forever at around 2,000 - 2,200 once it first started or after a couple minutes from a long run...</DIV>
<DIV> </DIV>
<DIV>Look forward to you responses...</DIV></BLOCKQUOTE></BLOCKQUOTE></DIV></BLOCKQUOTE><p>
