This is something mine will certainly need before going back on the road sometime in the coming spring. Thing is, when I took the manifold off of one at the breakers, which was in an awful state, I couldn't help but notice the equally rotten build up still left in the head.
Just wondered if anyone has successfully cleaned these out too, as seems like half a job cleaning everything else and leaving this lot. I realise any of that loose crud making it way down further could be a real issue.
Can it be done???
