After spending many years refurbishing my 1989 VW T25 Camper which is fitted with a Waterboxer DG Series engine, I finally had to give up on the carburettor.
The original Pierburg 2E3 was suffering from issues, but a service kit and readjustment didn’t fix my problems, which were that it didn’t start from cold, ran lumpy, and until it warmed up it would stall when opening the throttle.
