Carburettor flooding. Help !!!

[RichM882]

Hi all. I have a really strange problem that I have not encountered before in nearly 40 years of working on motor vehicles. A month or so ago while driving her she coughed, spluttered and died at a road crossing. Fuel was spewing out of the top of the carburettor and the inlet manifold was awash with fuel. I removed the Carter BBD and cleaned loads of crap out of it and checked float and needle valve. Confident I had eradicated the problem the next day I started her up. The very same thing happened again.I have put a brand new carburettor on today and lo and behold she is exactly the same. The fuel inlet is damp too as if there is a ridiculously high amount of pressure being created by the fuel pump. Has anybody ever experienced a pump go rogue ?

Your problem is new loads of crap being pumped out of the tank and holding the needle valve open. Put a filter before and after the fuel pump. Carry spares. When the truck won’t go 60 mph anymore it’s time to replace filters.

^^^^^ Exactly

Dump Fuel and check for what kind of contaminates are in there.

Pull tank and look for rust. Rust has to be the worst.

Crappy fuel, is the bane of every internal combustion engine ever invented, or that will be invented.

A discreet golden rod filter, AFTER a THOROUGH clean out. (Including fuel lines).
