What is the initial setting for the idle screw

I also have a 1976 Puch Maxi. My Clymer guide says:

1. Place moped on the center stand.

2. Start the engine and let it run.

3. When the engine is warmed up, turn the idle adjust screw with a screwdriver to reduce engine speed as much as possible so that the rear wheel does not turn (the engine speed should be between 800-1200 rpm). Speed up the engine a couple of times and let it slow down. Recheck to make sure the rear wheel doesn't turn.

4. The engine should not stall when coming to a complete stop on the road. If it does, readjust the engine idle screw to a SLIGHTLY higher engine speed.

I hope this will help you out.

about one or 1 1/2 turns out. but it can vary with the carb setting and any other mods.-jason

There is really no such thing as an initial setting for the idle stop screw on that carburetor. It is not a mixture screw. It is simply a 'stop' which the slide sits in top of when in the down (idle) position. Its only purpose is to determine the idle speed by virtue of holding the slide up (open) a very small amount when you have completely let go of the throttle twist grip. Screwing it in causes the slide to go up slightly thus increasing the idle speed. Turning it out does the opposite. Just set it to get the idle speed you want. That's all there is to it.

yeah greg, also if your throttle cable isnt adjusted right, your idle screw will do absolutly nothing.-jason
