Happy riding.

It' complete trial and error, but you'll get there.

This is the image of Vespa LX carburetor.
Not modify the idle with engine cold, but after 15/20 minutes of use on road of it.
Turn 1/16 the screw signed as "B" clockwise, after modify hold the throttle to maxium and release, repeat 2 or 3 times and feel your engine, if idle is correct ok else, turn 1/16 at a time and re-test until the idle is correct. Remember the rear wheel don't to must spin.

Simple to do, but you may find after adjusting, then riding, that you need to open things up and adjust again. You'll find what feels right to you.

You can use an inductive hour/tach for a motor to check the actual rpm. I report on this in Poor man tach

After trying for months to locate an affordable shop tach, I decided to try a different route. Smorris has a nice write up about using a tinytach in the Technical section. I didn't want to wire mine in permanently, and located an inductive hour/tach from my local Honda power equipment shop. I ended up with the Hardline HR-8061 model which runs off of a single line wrapped around the spark plug wire. It cost me about $40, but I have seen them less expensive on US websites.

What I liked about it is that you do not need to hard wire it in. The 22g wire can be inserted into the unit, and then removed when you no longer are using it. This was important, since I understood these hour/tach meters do not really stand up well inside the engine compartment. I've left the wire attached to the spark plug wire, and just tied it off to the side of the engine compartment for when I want to use the tach.

It is slow, and refreshes in 10 second increments. So you have to be patient when setting your idle.

Let the leader engine warm up completely, then stick your hands a few inches away from both bikes exhaust- you can easily judge when the exhaust puffs are the same rate. This is how I adjust my wife's scooter idle. Harvey
