To Wakayama City

The signs of fogging on spark plugs in air-cooled VW 1600cc AD motor obliged to adjust air volume adjust screw open 1/8 to increase air volume. This adjustment was very slight one but the effect was great to obtain good mixture ration.

The distance on the highway from OSAKA to Wakayama was enough to improve the performance of the motor with the fuel supply of Showa Shell High Octane Pura.

I realized when replacing distributor, this Flat 4 motor had been operated under seriously worse condition, without both vacuum and centrifugal ignition advance of timing, so the healthy combustion cycle must be prevented by ill ignition timing all the time.

So, running on the highway with Pura at good ignition timing brows away dirty material in the combustion room inside, the adhered inconvenient materials like carbonated dust, sludge and vanish. Actually the performance of the AD motor improved after few hours of cruising on the highway.

We have some talk about Mybows Chiaki, our opinion came to a meet together that he is an indispensable person in Air-cooled VW field because of his enthusiasm like an American Fire Ball in Japan Tokyo!
