my '88 scala has been running super lumpy on idle. When driving it runs alright and will tick over ok(ish) on choke.
It has a webber and ive changed the sender, fuel pump and carb gasket, all the vacuum hoses seem to be fine. i dont know if it could be an air leak but from where?

plz help this is baking my head!

Maybe inlet manifold?

I heard that spraying 'Coldstart' on the vacuum hoses can reveal a leak.
