New to running a scooter , currently running a Vespa P200. It seems to be running very rich. Starts up (even on the coldest of mornings) with hardly any choke, and the choke has to be shut straight away before I can ride off. It seems to be running as though it is on full choke all the time and the carb’ seems very slow to respond. I have tried adjusting the mixture screw but this has made very little difference.
I am considering buying a new carb’ , in the hpoe that this will sort the problem.
Any suggestions would be much appreciated
