Check your jet sizes and fuel pressure,you will most likely have to change the jetting as it must be running too rich.

The jets have been reduced to the lowest size as i was having more problems flat spots and stalling before they were reduced

Were the kads torn down, inspected and cleaned before being bolted up ???

Is the fuel pressure OK ??? (you only want like 3 PSI, and yes a standard VW mechanical pump can exceed this)

Ah well, better than plugging fowls, which is a foul practice.

Was going to suggest you chook them away, and get hotter ones......but I chickened out.🙄
I'd rather wear a Beetle out by racing it than by polishing it!

Check the needle and seat isn't blocked! A lot of later model kads are stuck even from new from the factory they aren't right even when they should be.

it sounds like ONE of the carburetors is running too rich...

You may need colder plugs...

are they long or short reach plugs?

Original VW plugs are 1/2 inch reach [about 12.5mm]
very short thread plugs..
