hey ...
Car:
67 327 350HP 67K miles. engine never taken apart. stock point ignition, new repro wires, all new NOS point/cond/cap,coil, new plugs.
fuel: Ethanol free 93 octane.
I have a interesting situation --
A:
if I have the VAC ADV disconnected, regardless of engine temp, I don't get a gas starvation when going WOT in 1st gear.
b:
if I have VAC ADV connected and engine and fuel cool, I don't get gas starvation WOT 1st gear.
if the engine temp is above normal (180-210) and been driving for a bit, and fuel is hot in carb - I get terrible gas starvation.
the car seems near dead, will not accelerate. if I go up to higher gear like 3rd, it seems to not drain the gas out of the carb.
the initial timing (VAC disconnected) is 6 degrees advanced. it will go up to about 16 degrees soon as I connect the vacuum line.
idle is set to 900 approximately.
if it is running the fuel down low in the bowls I have no idea if is the front or back.
the carb is original and has been professionally restored. 99 % sure the jetting is stock front and rear.
the fuel pump is like brand new and AC Delco.
no place for air to get sucked in - all rubber lines are new.
So why would I not have issues with no VAC ADV but they show up when I connect it?
this one has me confused somewhat.
Any help is appreciated..
Thanks
Bill
