'73 Super Beetle
Posted: Fri Jun 09, 2017 8:40 pm
Mick from Euclid Foreign Car brought his 73 SB in saying it hesitates badly just off idle. This SOB was just about undriveable at light throttle, I don't know how he put up with it so long. I thought for sure the accelerator pump was gone but it was fine! (new aftermarket 34PICT)

1. Hot air tube missing.
2. Hot air control vacuum hoses missing.
3. Bosch 009 with no vacuum advance. (Yech!)
Basic tune-up, verify TDC using the piston stop tool. There was a TDC mark on this pulley but who would have known which one it was without using the tool. I marked TDC and 30 very clearly for setting the timing.
009 is gone, replaced by a vacuum/centrifugal dist. Vacuum advance hoses and proper steel "loop" tube. This prevents fuel vapors from settling in the can and rotting the diaphragm out. All new ignition except plug wires. Hot air tube, vacuum hoses to control the flapper, and amazingly the little thermostat and flapper worked properly. Adjusted the brakes (out by a mile), installed a speedo cable so he knows how slow he's going, lubed his shifter bushing which was starting to seize up, and set his tire pressures correctly. I cleaned and checked the choke, checked tranny fluid, capped cold (dirty) air inlet on air cleaner and other stuff.
The difference in how this car ran was like night and day- hesitation gone, more power, probably a lot better MPG, mostly from getting rid of the Bosch 009 and going to a dual advance dist. He was happy.
