The last day today

Bon holidays over today with few results as usual. Residual tasks must be digested today, a pitching stopper replacement, trans-axle position sensor overhaul and room cleaning on XH200 Opel B-Vectra, deserted for long time garden cleaning.
Mental preparation must be done after the holidays.
Description later:

The ceramic part of spark plug was white with no color, black nor brown, this phenomena shows too lean mixture. So air volume adjusting screw was adjusted again to richer direction with screwing-in 1/8 rotation.

All the motor reaction and performance were improved so much reminding me of dear memory with WEBER 40 DCOM carburetor equipped PEUGET Talbot 205 Rallye.
The idling adjust was the only key to obtain good performance and the exactly the same thing is said on Solex 34PICT3 carburetor equipped VW 1302 Super Beetle, air volume adjust screw position.

Filing on contact points surface in voltage regulator could recover the adequate performance on fuel gauge stylus appropriate position.

Thanks to the rear toe direction(thrust angle) and total toe value, my Beetle goes straight like an arrow at any speed, of course no adjusting steering centric position.
I can afford to wear seat belt using both hands while running.

KAYABA scissors jack was repaired by the replacement of piston cylinder sealing material.
Only the application of butyl rubber squared shaped ring is not enough, deformable rubber is easily comes out from the clearance and the obvious pressure leak happens.
So the factory designed to insert some hard deformable engineering plastic material. Over 10 years use destroyed this plastic material ring.

The KAYABA factory does not supply the tiny plastic ring part only, they oblige users to return to the company for full overhaul, expensive at all.
Almost of the jack with this critical problem must be thrown away as it was broken with pressure oil leakage.

But for this special plastic ring for preventing deformation of rubber material sealing O ring, 1 month would be the life if used without countermeasure method.
The same plastic O ring is set on the bigger operative cylinder.
I happened to come across very suitable plastic O ring in my junk box.
The life of rubber sealing material would be extended far longer than before without this plastic ring.
