poor acceleration

[twinnynolan]

Hi all,
Wondering if anyone can help, my vespa idles fine and when i accelerate slowly it is also ok. when i try to open her up a bit more or increase speed quickly she just die,s on me. then i can start her straight away and she idles fine again. does anyone have any ideas.

could be fuel starvation, check fuel pipe, filter, float bowl, cleanliness of mainjet and emulsion tube. The scoot sounds like everything on the pilot jet side of things eg ; starting and slow throttle is fine basically from closed to one quarter throttle, then it all goes tits up. ie from one quarter its getting too much or not enough fuel thus upsetting the fuel air ratio. Ensure all your jets and carb box are clean and secure aswell as the airfilter.

Its all specualtion imho of course
