[Andy Pickering]

When did the problem start..had you changed anything prior to the problem...what top speed did it have before the problem..

no experience of them but have heard it said .....but if it ran ok before with a jetx ...thats not the problem

does it feel like a rev limiter (it seems to stutter at higher revs under load ) if it does its either pick up or lt coil or both

thrash it in 3rd ,,,,it could be your not getting up to speed in each gear so when you change into 4th theres not enough revs and it bogs down if your not very experienced on riding a lambretta let someone who is have a go on it who is ,
