[TR] TR4/Webers - that banging noise

[Dave Connitt]

I wonder if you have a bad wrist pin? Probably not, that would make noise if
the plug wire was attached or not though. Before you remove the head, can
you try replacing the rotor and distributor cap? You might have a carbon
track trying to fire two pistons at once. It would be easier than taking the
head off. Run a compression check too first..
