YS 140L Question

 Put a 16x12 on it to load it down to around 8200. Sounds like your low end needs adjusting. It should come back to 2000 instantly or quickly when pulling throttle back to idle.Adjust the throttle trim to give you the 2000.Then adjust the low end for the best idle at 2000.The low end is a air bleed type and comes into play around 2000 rpm.Turn it CCW to lean it and turn it CW to richen. I think thats right.

> 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...
