Don.. he doesn't need to fix it. just to start it..
Flip the kill switch up.. normal this means On...
on the right should be either a clutch or decompresion leaver
Also make sure when you turn the pedas.. that the motor turns.. easy way is to try it whil somone has there finger over the plug hole.. it will push it off.. you can also look and see if the magneato turns whwen you pedal.. if not then your bike motor is not engauged and there should be a switch you flip to lock pedal to the chain so it turns the motor over.
make sure you turn your gas valve near the bottom of the tank to open.
Then all you shoulc have to do is pedal a few times to start it up.
If it has a decompresion cable.. then it will look like the lever has a cable that run to the bottom side of the motor.. this lets some pressure off while you fiorst try to start..
If it has this then you simplke hold the lever in as well as the choke (probly both small leavers)
and let off the decompresion after you start to pedal. this will cuase it tog et harder to pedal but is nessasary to start it.
I think the clutch type is done the same way.. but not 100% sure.
if you get it to pop over a time or two.. then you probly just need to hold the choke lever down a little longer until the motor warms up .. like a chain saw..
if nothing happens.. then try what Don suggested and read freds guide.. its great to find problems.
I wish there was a general starting procedure page here.. but alot of mopeds are a little diffren't and I guess it might be hard to make a good one.
I ahd the same problem as you.. when i first got my ped.. i didn't know what did what so how the heck was i gonna know if it was broken or not.. hehe
hope that may help.. if you email me me what yo have tried and discovered i can try to help more.. im not the greatest moped man..but I think i have learned alot since i first got mine not to long ago.
