Preparations for cold

The coldest morning we had before dawn today, below zero degree celsius. The over cooling tendency of air-cooled VW 1302 Super Beetle has increased non-negligibly. Additional 5 minutes choking interval is necessary, otherwise it is impossible to continue idling rotation of AD motor. Deeper consideration led me to several ways of countermeasures.

Just simply rotate more counter-clockwise the automatic choke module.

Add the adequate resistor in series connection to down the voltage on bi-metal actuator's sensitivity of the module.

Replace into new parts, the broken parts of the thermostat actuator that is criminal causing this inconvenience, very difficult to acquire now that is not reproduced now all over the world.
Some experiment must be necessary to establish the solving conclusion for upper problem.

I gave up to insist on the theory to sustaining the life of car batteries and I would purchase new ones, B type and D type promptly. Even for new battery, additional and initial charging are necessary.

The brake master cylinder in BC7 SUBARU Legacy LSi US model would be performed, periodical replacement genuine parts has been prepared already, because no servicing had not been done since 20 years ago after the production, go ahead immediately before any brake trouble might be triggered. Brake fluid type 3 must be obtained.
