Wreck removed

The wreck of air-conditioner in the cabin of VW1302 Super Beetle was removed thoroughly today leaving big hole on the rusted rear foor.

The construction of the cooling device for setting in the cabin had reasonably two blower fans, one for condenser and another for evaporator.

The weight as heavy as 20kg surprised me so much, because I though it may be about 10kg

It goes without writing that the improvement of steering reactions in relations with rear axle response.

I remembered the saying, "Weight saving on automobile is the most secure tuning up method.".

The lack of warming up interval by the automatic choke system obliged me some experiment, applying 680 ohm resister setting in the heating module wiring serise connection.

The value of 680 ohm made the module action impossible to open the butterfly at fully opened position and the choke diaphragm had been kept in action leading to operation under a bit richer mixture condition.

As the almost of all informations say, richer mixture driving brought so smooth rotation of the AD motor.

The diaphragm for the additional fuel in first idle stage may be possible to control the air/fuel ratio mechanically to seek the best mixture condition on actual driving test running.

There is another way to overcome the lack of warming up ater the first idle stage, utilizing the nipple for distributor vaccum advance and vacuum retarding, I may make bypass air circuitry including solenoid valve on the way, as the parts is prepared already, I can go any time I want.
