Why would my carb fill up with water when I fill up the radiator?

 

Failed intake manifold gasket or bad head gasket or a crack in the head

Allowing coolant to flow into the Carb

Coolant hose connected to the wrong place??

 

Yea I thought the same but the head was just reworked. Talked to a guy I went to school with all he has dealt with his whole life said that the timing chain gets lose sometimes and rubs a hole right in the water jacket in the timing chain cover. Gonna pull that off and check it. Oh and also I permatex ALL my gaskets so I have a fail safe on the gaskets failing

 

Timing cover hole will allow water in the crankcase, not into the intake, your friend should of known this
You have a problem with an intake port somewhere

 

Timing cover/timing chain would have been off when the head was redone, the cover and timing chain guides should have been inspected at the point.
Doubt timing chain slop is the culprit

 

Just because the head was done does not mean it was correct

When did the coolant in the Carb start??

Curious how this ends !!!

 

Ok, I started the engine to make sure it ran we before I put the radiator and all in just let it run for around a solid minute. I threw the radiator in and filled it up. After about the second gallon of water I saw a leak from a vacuum line so I in plugged it and noticed the carb was slap full of water. So I went by process of elimination... pulled head going to recheck for cracks again, checked timing chain cover no wear holes, head gasket never even got hot enough to seal but no blow outs. Intake I looked but couldn't feel or see any cracks. IDK what else is left other then a cracked blocked... IDK

 

Three things to check, but I really can't imagine anyone of these causing such to occur.

The AAP (auxiliary accelerator pump) on the carburetor is controlled by vacuum switch mounted in the intake manifold. It is located in the path of the engine coolant. The two are connected via a vacuum hose. Check that no water is in this hose.

Check the large hose for the PCV vent. It is located in between the carb and the valve cover gasket. This would most likely flood the cylinders, though.

Lastly, the bottom of the intake manifold is feed with coolant. Check to make sure the gaskets are functioning. This would also most likely flood the cylinders.

Actually, one more thing I thought of, a coolant line is connected to the OVCV (outer vent control valve) of the carburetor.
