Modern Vespa

Hello its, been a while now
Iv got this '76 150 super, and it been trouble since iv had it and its beging to get borning now.
This time i find that it keeps cutting out when i drop revs, when i change down gear and when i stop, someone said it could be dirt in the carb?, iv had the plugs changed, but the electrics are a bit shot, i have to keep the lights on,
What do you rekon?
Any help would be great.

Well, your description isn't totally helpful... but i'd guess that your carb needs both cleaning and adjusting ... particularly the jets need cleaned out and your idle screw needs set. It's wound out too far right now and needs dialed in.

Thanks man, ill try that, its only started happening in like the last month or so. Are there any generic problems with 150 supers you know off??

no, not really. You're describing something that happens to all old vespas. It's a 5 minute job to fix, and once you figure it out you'll know for the next time it happens.

Your help is greatly recived,
im no good with engins and oil and im starting to get a bit anoyed with the bloody thing,
Thanks, sounds like you know your stuff.
