Help: Anyone know anything about mopeds?

[omj624p]

My nephew got a Peugeot Moped, and a few days ago it just cut out and now wont start.

 

I just took a look at it, to check the basics. The spark plug is sparking. There is fuel getting in.

 

I warmed the spark plug with a lighter and it started, but it ran really rough, and when throttle was applied it died.

 

Basically I have 2 questions:

 

1. Does anyone know what might be wrong?

 

2. It has a 12v battery which is almost flat. Can I jump start it like I would with a car?

 

Cheers for any advice...

I assume its a 2 stroke - has he put any oil in it?

Oil? Will have to ask, but I doubt it. Where? Why? How?

should be under the seat

theres quite a few things that could be wrong and you was probably right to start with the simple fings ,

 

1) OIL

 

With a 2 stroke underneath the seat where the helmet hide-away is there is also a 2 stroke oil bottle that has to be filled , if it has been run without or has has been filled up with petrol and there is no oil then it will start with a hot plug but will not run for long and also not do the engine alot of good as they are self lubricated unlike cars which have a dip stick etc , the engine still has oil in it but a very minimum just to keep the main arteries freely moving but the 2 stroke which is added lubricates the piston etc .

 

2) EARTH-COIL

 

behind the front fairing you will find the wiring loom , like many cars especially fords mopeds have a habit of getting corroded earth points so follow the wiring loom and find the main earth point give it a clean with a bit wet n dry or a flat headed screwdriver and tighten it back up again , you will usually find that the earth for the lights and coil are connected in some way so when you find it the coil shouldnt be to far away , again check the earths and possy wire as you would on a car then do the spark plug check by holding the lead with a plug in it against earthed frame etc and kicking over to ensure that you are getting a strong spark .

 

3) AIR FILTER

 

because two strokes are dependant on compression for them to start the air filter should always be kept clean and made sure that they are replaced every so often to keep the air intake to a maximum, on the back of the carb you will find the air box in which the filter is situated again like a car , it is very important that the filter is clean and has no crap in it at all because if the carb is starved then it wont start .

 

4) AIR MIX

 

if you have a strong spark and you have made sure that the petrol is running freely into the carb then check this next , on the side of the carb there is a air /fuel mixture screw if there is to much of either it wont start or will start and run lumpy , the standard rule of a two strokes is 2 1/4 turns , so screw the little screw in all the way and mark it tip x etc then count 21/4 turns out and you should be nr on to the standard factory setting , it may need a little tighten or maybe a little bit more lose but you can tell by how rich it is running by the smell of the oil that you get when it is started .

 

if it isnt any of the above then take a look here to see if there is anything else that you can do

What age & model is the Peugeot?

 

Most Peugeot's have engine immobilisers operated by a transponder in the key. PM me with the age and model & I will see if I can be any help

Quality work Posse!! :D

 

Ronnie Barker would be proud of your word play

I use to be a mech for pizza slut so worked on millions of the bloody thing and pergots have rubbish electric's!! Which one is it quite a few are 4 stroke now, n if it is 2 stroke they tend to seize sold with no oil.

 

Is it a carbed one or injection?

 

Get a new plug (they eat them!!), loads of carb cleaner down the plug hole, spin it over to get the excess out, plug back in the try n start it, if its a carbed one full throttle will prob work if its an injection throttle must be closed then pin it when it starts.

 

Try spraying carb cleaner through the carb or try taking the exhaust off cos they clog up with old oil or the cats can collaps.

 

Hope some of this helps

 

Good luck
