Have tried a 40, 45 and a 50 slide and have tried with chokejohnny650 wrote: βMon Oct 01, 2018 1:23 pm I'm inclined to agree with Daggs that it is a carb issue .
Clearly it is only effecting the throttle pick up off of idle by your description .
The idle is presumably stable so rather than the Pilot jet or air jet it could be the slide...... the slide is responsible for pick up off idle to approx 1/8th of throttle range.
Try this simple experiment. next time you go to pull away apply a little choke and see if that improves initial pick up. if it does pick up better then it would suggest you need to change your slide to a richer one .

crikey don't ya just hate intermittent sparking issues .
Its probably worth going over all your ignition system connections and earthing points and give them a clean . Its starting to get damp in the mornings and that can sometimes uncover lots of poor electrical connections

All sorted now - combination of a couple of things I think. Replaced stator so now getting a good consistent spark, timing reset at 18 degrees, also changed slide to a 35. Scooter is starting well again, first or second kick and pulls away nicely, not perfect, but much much better than it was. Now I have an oil leak - haha - always something!!!!

Where is βoilβ leak from?
You may be richening up your air mix, by going to that size of slide, to mask an air leak.

Because you changed 2 things,now you dont know if the new stator plate cured the problem or changing the slide cured it.

Oil is definitley coming from side casing - however, I intend to do a leak test over the weekendstorkfoot wrote: βWed Oct 03, 2018 10:20 pmWhere is βoilβ leak from?
