Bob,
Thanks for the help, I'll look into all of your suggestions. I did look at
your site's trouble-shooting section before I posted, this is just my first
bike and I'm a computer guy not a mechanic (although I hope to learn enough
to be dangerous) so I'm a little apprehensive about messing with anything
until I have a firmer grasp of the material.

 Hello Matt,
Unfortunately, there isn't any feasable way to add an electric starter to
the Puch's, since there are no openings to where a starter cog can enter
into the crankcase. You can eliminate the want/need for this starter, if we
can get your idle straightened out. Again, as mentioned before by others on
this subject, there can be one of several reasons that your idle isn't
working so well. First of all, have you tried to adjust the idle screw
itself? There is a flathead screw on the outside of the carb, that can
adjust your idle up and down. (sticky throttles cant cause your problem by
the way, it can cause excessive rev'ving problem though, idling too high).
If you have already tried this, then other options will need to be tested.
Check around the cylinder head while the moped is running, and see if you
can feel any compression leaks, checking all the way around the cylinder
head, being cautious NOT to touch the exhaust manifold or cylinder/head, to
avoid a nasty burn). If you find leaks or air escaping, check your head nuts
to insure they are tight. (don't overtighten, they WILL strip out if not
careful). If tightening doesn't resolve a compression leak, you may need a
new head gasket. Also, check your carb. Make sure the carb is seated all the
way to the back of the intake manifold, meaning, when you loosen the carb
screw at the manifold, make sure the carb is pushed onto the manifold all
the way. Sometimes when folks work on the carb, they do not seat the carb
all the way onto the intake, allowing air to enter from behind the carb, in
the slot behind the screw. Clean the carb. When you check the seating of the
carb, and if you haven't done so already, remove the carb and inspect the
bowl. It should only be hand tight, and remove fairly easily. See if there
is old gas/oil gummed up in the bowl. If so, take the carb apart completely,
and clean it using carb cleaner or gunk. Insure that the brass jet is also
not clogged. Timing and points can also be an added problem, that can be
looked into later, if needed. Try these steps first and see what happens. I
also have some troubleshooting tips online, if you would like to go through
them, and try other possibilities. Go to the "Troubleshooting Tips" at
http://www.puch.net/ . If you have any other questions, feel free to email
from the site, as I don't get to this board as often as I would like.
 Regards,
Bob

Hello all.
I bought my magnum II, it has 2500 miles and a few scratches, but is
quite nice. A few questions:
Is it possible to purchase an electric start (key/button)? The peddle
start works fine, usually first try, but I'm worried that if I need to
do it while on the road (say at a red light) cars behind me may be less
than patient.
It doesn't idle very well, If I'm not accelerating the engine
usually shuts off, but my friend said this was probably gunk in the carb
and/or a sticky/faulty throttle. Anyone else have any other ideas?
We did note that when it does shut off, pushing the choke back in
causes it to start up again w/ just throttle. Is this a common
problem?
We plan to rip everything apart this week and clean, grease, oil, all
appropriate parts. Any words of advice?
Also are there any other moped riders/clubs in Maine (Portland)? It would
be nice to ride with someone else.
