Why does my 73 Super Beetle keep stumbling?
Once the rebuild of his ’73 Super Beetle was complete, Dave still had an exasperating problem with the car “stumbling” on acceleration — whenever power was called for, like even after a shift change, the engine would stutter and sputter and sometimes die. It initially seemed to Dave that the accelerator pump was not giving an adequate “squirt.”
Where does the power come from in a VW Beetle?
Power comes from a GM crate ZZ4 350, seen here with an L98 tuned-port intake as likely pulled from a C4 Corvette. Installation looks to have been done pretty well, though details are very limited.
Is there any problem with acceleration on a VW?
Take it for a test drive, and acceleration is great: quick, with no real flat spot. As long as I keep the pedal down, there seems to be no problem. However, if I let up on the gas and coast, the rpms will drop and drop, to the point that the gen/alt light flickers, and its 50/50 as to whether it stalls once I get below 10 miles an hour.
Why are the heat risers on my VW not working?
Given a heads up from a reliable source, Dave removed the heat risers from the intake manifold (the came as separate pieces to the manifold) and found that the flanges on the header (to which the heat risers attach) were blocked; that is, they had not been drilled through into the header pipe.
How did Dave remove the heat risers from his VW?
Dave removed the heat risers (easy since they are separate pieces to the intake manifold), then drilled down through the flanges on the header so that exhaust gas could flow freely. Interesting side note– Dave was confused when his intake manifold arrived from Aircooled.Netto find the heat risers as completely separate pieces.

From a number of different sources, Dave has learned that the engine stumbling on acceleration (especially when accelerating through a corner) may be due to one or more of the following (in order of ease of repair) –
Why does my car stumble every time I push the accelerator?
This lack of heat to the intake manifold caused the extra fuel provided by the accelerator pump to just sit there under the carburetor as liquid, rather than being vaporized into the fuel/air mixture. This caused the car to stumble every time acceleration was called for.
