[gedyeates]

hi everyone
i hope someone can give me some ideas,
my vespa p150x revs nicely when still, but then put it in to gear ,ride around for about 5 mins and it cuts out ,it is smoking a lot as well, i dont now wheather it is piston rings or to much oil in the fuel , HELP
THANKS GED

have you checked the colour of your plug? this will give you a better indication of how you are burning fuel. also, how is compression?

if it cuts out when hot and wont start without choke its probably crank seals, see if the gearbox oil is low or smells of fuel
