Ran fine last outing.
Now it will start, but barely runs; very rough. Unable to increase rpm at
all.
All comes to an end in <15 seconds, often with a backfire.
Hint: Last time out, it got very hot. Got caught in road construction a mile
away. Approx 220F+ when I parked it. I suppose the fuel likely boiled in the
bowls. Do not have a spacer or heat shield. Ran the electric fan, with hood
up, for 20 min after parking. I didn't check to see how hot the temp crept up
after I parked it.
What I have done or checked today:
-The fuel pump was real slow to pressure up this year, so replaced that with a
new one from SS. Pumps up fine now.
-Replaced the fuel filter and blew out the fuel line while the pump was out.
-There were many black flakes in old pump. I suppose this is tank coating. I
presume the inline fuel filter trapped any of this prior to reaching the carb.
Took the (paper type) filter apart and there was a bit of the stuff.
After the above work was completed, identical result. Squeezed the throttle,
with the engine off, and the carb appears to be delivering plenty of fuel.
Holly 1850, rebuilt 1000 miles ago. Engine = internally stock 302. Mods=Offy
360 manifold; Mallory dual point ignition; Accel Super Stock coil.
I need the car for an event tomorrow. What am I dealing with here??
Thank you,
Gary Pointer
