sunday night I kept stopping then gets going again like the ignition is being turned off now wont start all petrol getting through ...now shouldn't the spark be a bright blue colour and keep sparkin till crank stops turnin cause it don't and its more of yellow spark

go through some basic checks first, check your spark plug is ok ,if it is take off your plug cap and hold against a flywheel bolt and see if theres a spark from the copper wire to earth and note what colour it is ,if its blue then try your plug cap back on and try it with the plug against an earth if it don't spark at the plug then either your plug cap is duff or your plug, if your spark is weak and not blue go to the coil and check your earth connection from the coil is intact and /or is dirty ,clean or replace earth terminal if no better try another coil ,to eliminate any ignition switch problems disconnect the outside green wire on the coil ,if you've done all this and still no joy check yor stator wires ,last of all get your stator checked out for a dodgy pick up and /0r replace the stator plate ,if none of this helps go to the shop buy a bottle of jack daniels and a box of swan vestas that way you can enjoy watching it burn and claim off the insurance....simples

tried everything but all to no good ..I took the fuel cap off AND paraffin was the smell I got now ive tried some weard things but parrifin or is that what shagged fuel smells like .........I bought it back on sunday and this is the 1st time ive looked at it

getting pissed off now new plug new ht lead fresh petrol ..even put juice down the barrol and nothing ...now I cant understand cause its a good strong spark so can it still be electrical

[ducksta]

have you done anything at all to the scoot prior to the problem changed carb etc

[soulboy]

no mate all the same apart from a bigger main jet ...... ive looked at the plug when kickin the scoot over and its not a regular spark sometimes it don't spark at all then it does again but its never a consistent spark its malossi 172 and it as bags of compression is it the pick up box

sounds a daft one but check your woodruff key on the flywheel hasn't sheared

[gavi4t]

and change the fuel

[soulboy]

ive changed the fuel and it aint the woodruff key

I had a similar issue late last year, running fine then the next day wouldn't run no matter what i did. As you have i checked everything, had a spark not a very good one but i had one, had fuel but put plug in and nothing. I changed the stator plate for a spare one i had, that was after trying a different CDi, lead, cap and plugs! it looks like the stator was starting to or had failed. did the same readings I would for a Lambretta stator and they were low on the LT side of life.

If you have access to a spare stator try it before buying one, plus try changing any part in the loop to eliminate them.

Hope this helps, Andy
