Still having problems

Project Blue is a thirsty car. Spark plugs are blackened. It is a dry black so that points to a rich mixture. I've cleaned the carbs as much as I could so I'm going to take desparate measures and cannibalize Becky. She's gonna be off the road as the tax is due at the end of this month and MoT is due before the end of August and isn't likely to pass without throwing lots of money at her so she might as well contribute to a worthy cause. What's left can then go to the Guru.
