Vapor lock again! Make sure the fuel lines are away from hot surfaces, or insulated.
Also, when it warms up, the automatic choke turns off, and the idle setting has to be set to run at that temp. There will be idle jets, maybe two, and idle stop setting for the linkage.

SOURCE: Just installed a 4 barrel Holley on my 1992 chevy

Many of such carbs required an insulator plate under them to keep from boiling the fuel out. Check with the junkyards.

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

When my 1972 chevrolet 350 4 barrel is warmed up it acts like its not getting gas and jerks and eventually dies. if i wait a few minutes it will start up but after slight acceleration it starts it aga


Good chance it is not getting fuel, or enough fuel.
When the rig is cold, the choke is closed. As it warms up, the choke opens.
If the metering jets inside the carb are dirty, they may not be letting enough fuel into the barrels. You could also have a vac leak that is masked by the choke until the engine warms up.

I have a 1981 ramcharger 318 4 barrel edelbrock carb. it starts fine, drives well for about 15 min but dies. dies quicker when 4 barrels kick in. about 2 min after dying it will start up fine and do it...


Those rattly noises are detonations,  caused by a very lean mixture. All the other symptoms indicate that the fuel flow to the carb is too low. Since you have replaced the pump and the filter, the only other things left to check are the lines and the tank sump. Or you could install a much larger pump.

2001 chevy silverado won't start when warm


Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.
