Hello Ray, The prior owner changed the engine from 1300cc to 1600cc. The serial number stamped on the block indicates that it is a 72' engine. When I purchased the car the prior owner said he was having electrical problems. He had an aftermarket air filter on the engine, after market collective exhaust. The first thing I did was change the exhaust to a stock German muffler. Next I replaced the chrome paper air filter with an original oil bath air filter. I got rid of the 12v "wet" battery and replaced it with a 12v Optima. The prior owner told me that he had converted the car to 12v however, on closer inspection I found that the only thing he had changed over was the generator to 12v. I changed the 6v headlights to 12v H4's, I swapped out the 6v armature in the windshield wiper motor with a 12v armature from Wolfsburg West, changed all of the bulbs in the rest of the car to 12v, changed the 6v voltage regulator to a 12v Bosch voltage regulator, changed out the coil with a Bosch 12v coil, changed the fuel cut off on the carburetor to 12v, changed the choke to 12v. Whenever I can, I purchase Bosch or German made parts. I pay more money for the parts initially but I feel that in the long run they fit better, more reliable, and have a better longevity than parts made elsewhere. I do not like to do things repetitively. I want to fix it once and move on. My next projects are to replace the 009 distributor with an original vacuum advanced distributor and get rid of the aftermarket fuel pump and replace it with an original fuel pump. The carburetor is a H30/3 Pict Solex and as far as I know it is the correct model and size for this engine. Greg

In general I would stick with the stock exhaust if you are using the stock manifold setup. In addition using a vacuum advance and the stock carb will result in lower cylinder head temps...

If you notice the stock mufflers ran a pipe down to a low pressure area so there would actually be a flow of exhaust through the intake preheater runners.? Not sure how much flow you get through even if the holes are drilled out.? Anyone know?

However, I removed the 009 that came with my 1500cc 30-Pic-1 carb equipped enginge on my '67 Ghia. I replaced the 009 with a stock distributor and the hesitation almost disappeared. There is one other thing thing that contributed to the hesitation on my Ghia (see below). Someone else has already described the importance of ensuring the preheat tubes on the intake manifold are clear (not blocked). As you know, the end of the preheater tubes are bolted to flanges on the exhaust. If you are using an aftermarket muffler, look into the flanged hole to verify that a hole was drilled into the exhaust pipe. I removed the aftermarket muffler from the Ghia to find that the hole was not drilled; therefore, no heat was transferred into the preheat tube. I'm not sure why they'd go through the trouble to weld the flange on the exhaust and NOT drill a hole into the pipe! Good Luck!

I now understand why the 009 stumbles. I enjoyed reading the articles and I now have a greater understanding of how the two types of advances differ in performance. Another plus is that I now know what is wrong with my Dad's 72 Super Beetle. He also has a 009 distributor. I do not understand why anyone would put the 009 on the car if it has so many problems. By what I read it is more of a step backwards in perfomance rather than enhancing performance. take care, Greg Brian wrote: > Greg, > > The vacuum advance works to advance the ignition timing based on > engine load > (the more load (vacuum), the more ignition advance).
