My Feedback: (1)

I maidened my Skymaster F-5 this week with a P140-RX that I bought new about a year ago. The first three startups were flawless. On the next three, there was quite a bit of flame, with flames reaching about two feet out the back of the tailpipe. I'm concerned about hot starts on this jet since it has a bifurcated tailpipe. Is the 140 getting too much fuel at startup, and if so, why did it change after the first three starts?

frema

it can be that the pump runs better
first the pump was maybe a bitt sticky
now when the pump has run more you need to sett the uacell settings back
maybe that helps
i had a p140rx too , but never saw any flames
