The strange thing with this whole matter is that the engine didnīt do the dieseling before , with the same heads, and the same pistons, the same plugs and the same fuel pump. Pressure at the fuel pres.gauge is between 5-7psi, and the transparent plug on the carb doesnīt show gasoline level to be high.
Only new camshaft (sharper though !), springs and intake manifold are different from the previous setup.
The old manifold , a Blue Thunder dual plane had to be taken off because water was seeping into the engine through some pore , which welding and rewelding didnīt cure.
I will check on the gas pressure issue though, and increase the spark plug gap to 0.050 as recomeded by MSD.
An adittional problem is that the outside temp here is about 95šF with a humidity of 80%. That is no good temp to go out and test a Cobra with its permanent footwell heating.
( By the way, does anyone know of a duct system to channel cool air from the outside to the footwell?)
Let you all know what happened after my test drive late this afternoon.
