I think Josh said he might of had one from his 4a quad bike carb setup that I could buy off him, so will see what that is Si!
I will be using a 4k head Stu which I need to pick up off Simon, But can' quite drive yet with this stupid wrist. Shouldn't be long tho. :)
Will try and find someone to match port it aswell for me, as the last fella I gave a head to did a bloody rough job haha
