Lean running 372xp

[thetoolnut]

I have a 372xp that's running a bit lean, i know that i can richen it up a bit by adjusting the low and high jets but by how much? and do i need a tach to do it?

Not richening the mix, hold it on WOT and turn the screw left/anticlockwise until it starts to 4-stroke, then drop it through some wood, if it stops 4-stroking it's done, if it continues, lean it up until it stops

H screw (H is for high revs, L for low revs), and WOT is wide open throttle (full revs)
