I have a Aerox that wont start, its a 57 plate it as a 70s kit on it, racing tuned.
It was running fine and then one day it just cut out.

I have cleaned the carb and put new reads in, new spark plug, new cdi unit,checked everything i can think of and still wont start.
As anyone got any suggestions please?

I have checked the magneto key and thats fine

I wonder if it may be the rings as thinking about it, it seems low on compression

Gary, March 2010

have you checked the crankseals ?and also does it have good compression if you push the kickstart down it should offer a good amount of compression being a 70cc .it could also be the woodruff key sheared on the magneto it keys the crank and magneto together in the right place and if it moves the ignition timing will go out.

Hi Adam, thanks for your reply and yes i was riding it at the time, i was going about 10 mile a hour as coming up to a t- junction and it just cut out.
The kick start is fine same as normal.

Gary, March 2010

did it cut out while you were riding it?were you going fast when it did it and was the kickstart stiff to push down afterwards?.
