So I finally got everything ready to go on the new 351w this morning. Turned the key and it started - idled at 2K for a few seconds, so I turned it off. Checked everything - unhooked the electric fuel pump (not sure why) - turned the key and it started again and idled at 850 rpms till the carb ran out of gas.

Now it will not re-start. . . I have never had this happen. MSD 6al, Reman Duraspark distributor, electric fuel pump (still working), Holley double pumper...

I have checked and rechecked top dead center - set the rotor on the 1 cylinder, set initial timing at 10* - anyone have some ideas?
 
i would think you need to prime the fuel pump again. are you getting fuel into the bowls now? if not, re-purge it.....my best guess. good luck.
 
I am getting fuel out of the squirters . . . and I am getting spark. I can't keep cranking on this thing or I will round of my non-roller cam...

Should I dump gas down the carb? That is what I am about to do . . . how much gas does thing thing need to start?
 
Not much! If you have not done this before with a carb (especially one that's being difficult) you cannot understimate the danger of gasoline. Consider how much the accelerator pump squirts in there. More than a sprinkle, less than a splash.
When I was still in the service, I read in a safety bulitin about an guy who was off duty doing eactly what you are contemplating. He held the cup of gasoline in his hand while his buddy stried to start the car. It backfired and he was set on fire. He survived. However, it's done all the time. And is an easy fix for stubborn carb motors sometimes. Common sense should prevail.

If it ran once, it should run again. I would consider that its flooded. Hold the gas pedal to the floor while you crank it to get air flowing through to evaporate the excess fuel. This "usually" works. Try this before adding more fuel to the fire. Make sure the plugs are actually dry and not wet with fuel befor tossing gas in the carb.
 
As it turns out - the plugs were oil fouled! Over the course of the build I kept putting oil on the cylinder walls to prevent moisture...must have had to much! Cleaned em and she fired immediatly . . .

12 minutes into the cam break in however, my radiator sprung a leak (damn electric fan rubbed through - couldnt hear the tick with the car running at 2500 rpm!)

Thanks for your help everyone
