I've got an old 1974 Vespa large frame VLB (VIN - VLB1TO174544)
I put a new carb on it 2 1/2 yrs ago, last week it started running rough and would die at stop light. I ordered new gaskets and pulled carb apart and let it and all parts sit in carb cleaner overnight. Next day put it back together and on the engine. It made no difference, problem persists. Scooterwest guy told me to run a small wire down the idle jet port because there seems to be something plugging the passageway. Did that but still no luck.
? Do you guys have any ideas? My next thought would be a new Carb. BTW I put in a new spark plug and road around for an hour and pulled the plug to check for carbon. Yup, lots of black carbon on the plug. Much appreciate any help you guys can give.
Thanks,
Bill
