Every 2 years legal inspection

The lead battery in VW Air-cooled Beetle 1302 was charged for preparing the coming legal inspection on Monday. A charging device is one of a switching power supply with 16V/2A, very gradual charging method for the least battery damage. Full charged condition is observed to discern the continuous bubble bouncing sound at 15.5V.
Additional charging ceremony is indispensable for over 4 years old lead car battery.
75D23L is utilized for my Beetle instead of European standardized one. The terminal diameter is the same each other and the physical property is superior to imported expensive smaller one, in addition, with the more capacitance at half a price.
Combustion firing timing is changed, much more faster at BTDC, because the checking condition is changed, removing vacuum advanced circuitry connecting while idling, actually the rotation is very smooth and acceleration is more. Let's see what will happen when exhaust gas is checked. I have some bitter experience on WEBER side draft carburetor burdened in Talbot Peugeot 205 Rallye, so I do have some courage and confidence to adjust there and to pass the inspection. Special standard for old vehicle is prepared in the Authority, the regulation value is looser.
Now, all the requirement are fulfilled for D-Day, the periodical legal inspection by the Authority at Hyogo Land Transport Bureau in Kobe.
