hi i was using my vespa last weekend and it ran fine, i have been away all week in the lorry and decided to go out on it today but it was a right swine to start and when it did start it will only run with the choke on,, if i turn the choke off it just cuts out unless i give it full throttle, if i set the idle screw so it ticks over fast and the take the choke off it seems like its starved of fuel i.e revving high as if its running out of fuel then just cuts out,, is this the seals? any help appreciated,, steve,, by the way its a t5 engine, regards .

steve, remove the gear oil filler screw and top up with fresh oil,if it takes quite a bit chances are when you start your scoot smoke will betlch out the exhaust indicating a knackered main seal. ( so bloody common these days) hoprfully just a dirty carb problem though.

hi just topped up the gear oil and started it but no smoke as such from the exhaust?? ive removed the jets and even swapped the 112 main jet that i put in for the sito+ for the standard 110 jet but still the same,,steve

Most likely crap in the carb mate rather than seals.
if youve done the jets, best get the whole carb off, clean out the filter, needle, bowl and the jet tubes as well.
If still no good, try running it with the filler cap off.
Again if no good, i'd be lifting the tank out and checking the fuel flow from the tank is good and steady, if not, pop the front off the tap and check for blockage there.
