Making the Weber 32/36 DFEV work on a buggy
The single Weber 32/36 DFEV is a great carburettor but requires careful setting up, it also needs a fully heated manifold with a good flow of exhaust gas passing through the risers and hot air feed to the air intake, in fact the more heat the better.
My original Weber was supplied in 2004 with the basic heated manifold and jetting, alright in the summer but suffered manifold icing during winter driving also the throttle cable coming through the engine fan casing did not align correctly with the carburettor.
Fitting the Redline Weber full heat manifold / throttle linkage and hot air feed to the air filter has overcome most of the above problems.
To ensure the Weber gets the correct pressure and amount of fuel I have fitted a Huco electric low pressure suction fuel pump in the engine bay

On the original Beetle exhaust system the hot exhaust gases from No 2 cylinder were fed to the manifold via the right hand side riser pipe through the manifold and down the left hand riser pipe through the exhaust header to atmosphere as shown above
The cutaway shows how the cold exhaust gases from the manifold were ejected from the exhaust header
