What a Plonker!

I've just spent the last 3 days trying to balance the carbs on the Spitfire - even bought a colortune today as a last resort as it was evident 3&4 were running rich. Plugged it in - good spark but no real fire!.

In frustration I decided to dissemble the carbs to get at the inlet manifold nuts just in case they needed tightening, took the heatshield off to find the gasket between it and the rear inlet manifold had missed the bottom bolt and was obscuring the inlet - what a plonker!!!

Put it all back together this evening, running really sweet now - just need to check the balance and mixture tomorrow
