I have got a misfire on my 351w motor, I have spark all round but it appears as though fuel is not getting through to cylinder number 4. I have a good spark and the engine starts fine but runs on 7 whether it is idling or when I rev it up.
I remove the plug on number 4 and it is dry and clean whilst the other plugs are a little sooty.
I have changed the leads, plugs, rotar, cap, carb and coil and no difference!
I have also done a compression test which was good and vacuum test which was good.
Anyone got any other ideas as it's driving me crazy! Cheers Tony
