I recently went out to tune my engine using your method.

I let the engine warm up, set the high end and then ran it at WOT for 20 seconds and the rpm did not drop. This all took a little over a minute. Then I let the engine cool.

I then continuously leaned the low end bit by bit following the 4 stroke popping sound all the way down to just above idle. Then I let the engine cool.

The engine transitioned from idle to WOT perfectly and ran very smooth all the way down to just above idle but still four strokes at 2000-3000 and maybe even a little higher rpm. Just above idle.

I am afraid to lean the low end more because I may have already leaned it in a whole turn.

Other than that everything else is factory settings.

How do you get this 4 stroking right above the idle to go away? Do you keep leaning the low end?
