I'm having problems adjusting my LSN and idle screw. I've gone through the tuning bible and can't figure it out.
Basically, either the engine idles too high the whole time, then stalls, or it idles too high, then when I turn the idle screw down, it stalls, or when I lean the LSN slightly, and hit the gas, the engine immediately dies.
What do I do?
Sounds like the LSN is to rich. Take the air filter off and set the idle gap to 2mm (about the width of a Xacto blade). Then start the motor and warm it up. Give it a couple of full throttle blips, listen to see how long it takes to idle down. Start leaning out the LSN until it does not idle down, then set the idle screw to the correct idle. At this point the HSN will probably be to lean, richen the top end until you see constant smoke while accelerating. Temp the motor after a couple of min of driving. It should be around 230. Only make small changes, in one hour increments, at a time.
It always helps if you are at the track and get someone to help that knows what is going on as you drive it.
Good luck and Happy Holidays.
