Help - need carbureta for 2.4L petrol for Kenyan safari bus

[Tommyson]

I have an old 110 pick up which was converted from a diesel TDI to a petrol some years ago in Kenya (before i had it). Recently we have converted this into a safari waggon for use by the family etc. Problem is that the carbureta (weber) is knackered and new ones in Kenya cost an arm and a leg. Was hoping to get guidance from those who know more than me as to where I can get a decent used or new one in Britain? I would then ship it to Kenya for instalation. The landy looks very nice on the drive but of minimal use without some thunder!!
