Worked on the Beetle a little tonight.
Here's another tool that's nice to have, a right-angle 13mm box wrench:
It reaches around the intake manifold body to get at the bolt at the back that secures the carburetor. It's a 12 point wrench, so it only has to have clearance to turn 1/12 of a turn, and it just has that much:
Here's the engine now:
Engine compartment wiring all connected, carb in, fuel hoses connected, throttle cable adjusted. To go: air cleaner, pulleys and fan belt, and the rear engine tin piece.
