    Doesn’t want to run smoothly when cold... starts OK but idles rough (not a misfire, just not smooth, ‘hiccups’ and falls off idle); however, if you keep it running, once warmed up it comes clean and even if it then sits for 8 hours, it will start and run clean, but next morning same deal?
    Not fuel (tank was cleaned and lines replaced not so long ago) ,I think not spark (I think that would be a constant issue), not air (replaced the air filter yesterday)... doesn’t blow smoke or unburned fuel - all I can think of is just doesn’t want to go out in the cold!
    Would a generator problem do something like this? Normally the light comes on when the revs drop but I fancy it is not coming on at the usual point?

    Any (sensible) ideas? Workshop is heavily booked at present.

    This is a very well known Bambino problem, you have the firing order wrong; it should be 2,1; not 1,2.


    Silly signature here to annoy KIAI

    The obvious has been mentioned: points,plugs leads.
    I doubt coil,they either work or stop...as my Mog just did.
    Loose disy..not so silly,..condenser.
    Geny? quite possibly but as you say you warning light should come on..
    I doubt dirty fuel tank as your usage is very regular but you could have some contaminated...
    Possible carby float or accelerator pump in carby,if it has one.,quite common.
    Has it been fitted with some sort of electronic ignition? I don't think so when I knew it.

    its an easy fix for any home mechanic like most of us on here repalce fuel, plugs ,check leads , balance resitor ? ,coilcarby, coil doubt it as they give issues when hot , i sugest warmer plugs or try a different way of starting ,,,,more or less choke sound to me as if she is flooding it on start .

    It would be really good if the problem is sorted and reported back, that would be a first for the Aussie section!

    Re-reading the issues,I'm going with internal carby issues.
    If it has a float there could be a pin hole in it....or the other couple of things I mentioned.
