Idling & Battery

The motor stability after cold starting in my VW 1302 Super Beetle has been influenced by the changes in ambient temperature, just the warming interval is not enough and the tendency of plug smoldering. As the intake manifold has some pipe linkage to warm the intake air, it must be clogged, inviting icing phenomena?

In addition the idling speed is not enough to warm up cylinders now, might be some clogging in orifice in the carburetor construction, according to my over 40 years experience with 30 automobiles I feel so. Some countermeasure must be worked out now.

I made up my mind to buy a new automobile lead battery for XH200 OPEL B-Vectra not as a genuine European Standard size but as Japanese D type battery with almost the same Electric Capacitance and with the same terminals on both side but not as the height, 20mm higher but acceptable in battery bay without any modification. Problem is the way of mounting fixation, some upper clump must be applied with hooks.

Additionally comparing them on the physical property and the actual performance as an automobile battery, there are apparent difference, once the sulfation occurred on the terminal surface, it's difficult to recover for foreign brand productions if special charging method might be applied.

I'm going to obtain new batteries, 40B19R for NCP10 TOYOTA Vitz and 55D23L For SXE10 TOYOTA Altezza.
