Formidable

I'm now setting Solex 34PICT3 carburetor on VW 1302 Super Beetle these days.
According to the information in the Web sites on the carburetor, '71 was the most struggle period because of Exhaust gas regulation for emission control, most confusing time.
Ignition retarding idling system with double diaphragm vacuum advancer, basically lean jets setting smog carburetor with accelerating pump 34PICT3 was adopted.
Displacement of 1600cc and dual intake ports were introduced in AD motor.

Sampling some datum while actual running test on ignition timing, then the results can be pasted into the specially adjustable distributor,such kind of devices are in the Web site market.

Because of upper reasons I feel it a formidable opponent to adjust the AD motor in the highest balanced condition, I'll do that and be sure to overcome!

Not to think over to find the reasons not to do, but to seek over the ways to conquer the difficulty, this is my way.
