Anyone know why this has happened I'm not sure if its corrosion or the have been burnt.. I did notice that car being out in the cold on MITP has cause corrosion on the outside of the carbs... all in one night..

The build up on the posts in the cap are caused by the reaction of the spark crossing from the copper rotor arm to the ally contacts causing a flux like build up plus a bit of damp causing the post to corrode quite common

Merv is correct there and on top of that the spark can get weaker as it has to jump a bigger gap.A new dissy cap is the way to go,They harden with age and heat and usually crack up (a bit like me really!)LOL
