Vapor lock

    I have a BMW 2002,
    When she's hot she won't start.
    I haven't really investigated it tbh but a quick Google says it could be vapor lock.
    Basically petrol evaporating in the carb.
    Anythimg I can do to stop it happening? Or at least a workaroun, perhaps a way to prime it.
    I do use leaded additive.

    Have a look here or here, could be many things, filter, float sticking....

    Good luck

    You can get spacers to fit between the carb and the inlet manifold to absorb heat, see if there is one available for your carb?

    Start with the basics does your coil get very hot? Change your coil over it’s a two min job.

    check where your petrol pipes run....maybe re-route them if near the exhaust or manifold
