if the engine is "RPM" stepping after the high speed run the LSN IS TOO RICH but wont need leaning much,

if the engine is holding a high consistent RPM normally hsn is just a tad lean,

you will find after a few minutes running if the lsn is too lean because at idle it will RPM step, as the rpms will rise (accorcording that your idle gap is around 1.2-.7mm open)

all these above things will depend on your linkage if you have it set up properly...

as someone said head to the track and ask someone for help.
ALOT of people get the top one wrong about the LSN and they are left without power.
