YS 140L Question

[Larry N Lisa]

OK...I've posted questions about problems in the past...Now this may be on the other end of the scale...

My YS 140L was very strong this weekend. I have changed fuels and I'm using PowerMaster 30%-DZ.

I know I'm turning too many RPMs so here is what I'm currently running:

1) Prop 16x11 (Prop Clearance issue for anything bigger than a 16" dia)
2) Hatori Pipe...Has the tab for mounting built into the pipe. Don't remember the number.
3) 1/2" Header (Black and Tony Stillman thought it may be the header from Australia).
4) 1/2" Teflon coupler from McMasters.

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.

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...

Look forward to you responses...
