In fairness to Pertronix (and to my embarassment), I must update my review. There was a wiring issue with the coil on our VW bug that was not causing any problems, but probably didn't allow the previous two distributors to operate at all (no spark). After the wiring on the coil was corrected (again wasn't causing any problem with the points distributor), I ordered another Pertronix Electronic Distributor. Installed it and it fired right up. Timing was solid and the engine ran very smooth. The Bosch 009 distributor hesitation has been significantly reduced.

Again, I feel the first two distributor probably were good. It is important to correct my comments so others feel confident to order this product. Very easy install and I would recommend this product as an excellent replacement for stock points/distributor.

I had bad luck with this electronic distributor---twice. First one was DOA. Contacted Amazon and they were fantastic! Sent carrier out to pick up from my door. Second distributor was sent to me and and same problem......DOA. Install is very simple---two wires (Positive and Negative). Followed directions and no spark at all. Had mechanic review install and confirmed it was installed correctly. Both times the vehicle was operational before installing new distributor.
I have no idea why I had such bad luck because the reviews are all positive and confirm easy install.

I had always thought my 009 dizzy was fine coupled with my 34 pict 3 carb. I can't believe how smooth my engine is now running. Ready for summer fun!

Installed this in my '74 VW Thing along with a Bosch blue coil. 5 minutes later she fired up for the 1st time in over 30 years!!! Instructions were good, with the exception of no info on where to connect the vacuum port on the dizzy. The port should be connected to the carb vacuum port pointing to the dizzy, just at or below the throats of the carb.
I also found that there is a rubber buffer under the rotor cap, in my case the buffer was standing up sideways and not laying flat, whoever assembled it jammed the rotor on and damaged the notch in the rotor, but not enough to need a replacement. Laid the buffer flat and reinstalled the rotor, no problem.
I had no problem with the o-ring, I lubed it with grease and the shaft went in just fine, others say to use the old o-ring but I did not need to.
Comes with the correct electrical connectors which is very nice, you don't normally get them with other products. The wiring is also long enough to reach about 12", so you can cut to your needed length and then crimp the connectors on. I added a protective sleeve and some shrink tubing to protect the wires.
Every VW dizzy with points should be replaced with a similar electronic unit. What a sight it was to see an engine that had been forgotten for 30 years come to life and run so well!

This distributor works great and fits well. There are two things to look out for, as pointed out in other reviews, but I will add some information based on my experiences that might help: 1) the spark plug wiring is different from my last 009 distributor - cylinder 1 is located one position counter-clockwise from where it is on the 009. 2) the o-ring is easily damaged. Even though I lubed the o-ring, I damaged it when pulling the distributor out, I think because I didn't pull it straight out and instead unintentionally angled it a bit towards the end. Interestingly enough, I found Pertronix's technical help online form and I asked them how I could go about buying a new one from them. After all, I felt I did the damage. They wrote back a few days later and asked for my mailing address so that they could send me a new one! That was much appreciated.

Easy to install and won't fail you. Other no name distributors that I've tried failed with a few months. I use this distributor in my 1969 Beetle, 69 Gia and 76 Transporter with years of trouble free performance..
