Problems

Though VW 1302 Super Beetle is cooled by air flow, the thermostat mechanism is equipped. As a common sense, thermostat is so controlled to control water flow while the coolant is cold at cold starting stage, air-cooled old VW Beetle has the same to control cooling air flow when cylinder is cold.

But this mechanical bi-metal actuator to shut and to open the air flow of cylinder cooling has some tendency to fall into dysfunction, fully opened when it is out order, causing over cooling phase after the cold start while a minutes.
Recent change of atmospheric temperature to below 10 degree celsius revealed this hidden inconvenience, lack of enough warming up period of time invites stool obliging a driver to open throttle valve.

Realized I that any unnecessary device had not been designed by the factory even 40 years ago, air flap actuating thermostat device.
I'm not sure that I could compensate the lack of thermostat controlling by adjusting the automatic choke controller. 5 to 10 degree counterclockwise rotation would prolong the choking phase?

The way of thinking "The client the first" that my son wants to invite for designing new laboratory would cause inevitable stress on the practitioner instead.
The reason why the designing by my son has introduced this time is to make it easy for him to come back to OSAKA, his mother's earnest wish influenced on the planning.
