11AD Super Beetle---Inspection by the Authority

Yesterday, lost I the periodical inspection on my Super Beetle held at  Kobe Land Transport Bureau.

Because the motor did not start, I adjusted point gap unnecessarily leading change of combustion timing. Too much Hydrocarbon was contained in ex-gas as a matter of fact. Adjusting #1 spark timing at 4 degree ATDC, CO and HC barance was obtained. 

To tell the truth, '71 model was specially modified on combustion condition according to inviting Emission control, double rubber plates diaphragm vacuum leading angle for retarding firing timing at idle speed, very strange vacuum diaphragm module was equipped. Consequently, ATDC position was engraved on the crank pulley in addition to BTDC Zero degree marking. ATDC 4 degree is the most convenient firing angle position for AD motor produced in 1971, so tuned in the factory. So, it is a very natural story to have passed the inspection at that firing position setting.

As for emission control, I could attained after secondary trial yesterday.

Next is the break lump activation failure, I know this is because of valve socket connection problem caused by some Oxide film. Disassembling the bulb holder and wire blushing will revive the circuitry.

Third problem was caused by head light axis, a pair of headlight was replaced into genuine parts, Hella H4. I'm not good at this new light distribution, Hi & Lo, this is why I lost this inspection. Adjustment utilizing the machinery is required. 

2 problem in relation with headlight and brake light are remained and they should reconfirmed at the Authority within 2 weeks paying additional fee 1,800 yen!

It's not fun when things go smoothly. It's interesting to move forward while solving the problems that keep pestering myself. Exactly the same thing is said in my business and in my hobby, revalidation on the proposition that had been solved if it is difficult is not so charming for me, but a completely new field no researcher has passed through is just fassinating. Probably, most of the engineers in the research and development must have a same opinion as mentioned above.

Curiosity and interest are the indispensable energy to live in this world!
