Chaps,

I was reading a post about a catasrophic engine failure caused by a carb being out of balance. I.e. the overall output of the engine was not lean or rich, but 1 cylinder was obviously running way too lean and it burnt out!

My question is...
Can anyone give me some advice on tuning my engine with respect to timing/carbuerretion?

I've got a 2 litre V8 with 4 twin choke Carbs and 2 distributors (so no more complex than 2 minis!).

I'd like to make sure everything's in balance and hopefully cure a lack of throttle response when it's been idling for a while.

Can you recommend any books or courses for tuning such an engine? Or give any advice at all about techniques or tools required.

Thanks in advance.

Dan

Thanks Nev for an excellent link.

Thanks too to everyone who replied. Am thinking of practising on a motorbike engine first, to get the hang of it before tackling the Ferrari.

Thanks again Nev.

I recently forked out £45 for a workshop manual when I could have downloaded it for free - D'oh!

...Although a Ferrari workshop manual with greasy fingerprints on it does have a certain amount of coffee table cred
