Colder morning required much more richer mixture for Solex 34PICT3 carburetor equipped on VW 1600cc Air-cooled flat 4 motor embedded my 1302 Super Beetle, the setting of A/F ratio has bee distorted in leaner direction because of ignorable fuel consumption. Stepping breath phenomena and hesitation while acceleration stage spoils comfortable driving. The smaller screw for air volume adjustment must be closed a little, 1/32 or 1/16 turn to increase fuel supply for all the stages. Now I am re-impressed the physical performance of recent computerized automobiles with the capability to adjust A/F mixture adequately in accordance with the change of external conditions, the outside air temperature and the hysteresis of the motor performance.
More careful checking on rear total toe value and toe direction, thrust angle, would be done on 1302 this afternoon, because tightening of rear trailing arm inner bush has made it clear that there exists some error on the adjustment item, it would be done by adjusting outer arm length in combination with wheel base length checking. Very precise measurement and adjustment with concentration investing keen and sharp intuition would be required to get some achievements.

I have set up a Digital recording system for Medical Clinical field, Canon EOS kiss body, Minolta 50/3,5 Macro Rokkor and US Washington Camera Co.180 degree rotating Special Strobe bracket. Fine transparencies with sense of reality especially of soft tissue would be obtained based on the technology nourished for as long as 40 years, mainly in silver salt generation period of time. But remember here, I have to do all the works by myself that had been done so far by the magazine company? It's so tough but rewarding enough?

Visited I Tenkawa village Yoshino in Nara Pref. yesterday for some good work on Minolta MD-Rokkor 28/2,0 in combination with Leica M9 Digital body. In order to adopt an old MD-Rokkor wide angle lens on M-bayonet mount, special adapter was manufactured utilizing a lens rear cap and a M body cap adjusting flange back distance to complete focusing at infinity distance.
As shown on the cylinder description, closing the iris ring to 8 obtains enough focusing depth from 2m to infinity to shoot ordinal objects, so range finder coupling is not always required for ordinal use. This is why I made up my mind to modify this dead stock lens produced while silver salt generation, over 30 years ago. Every lens maker is designing them utilizing computer analysis method to obtain the best solutions, so the physical property are the similar or the same, no difference is found in the way of expressions. This Minolta MD-Rokkor 28/2,0 lens is one of a relatively rare production with small amount of production in number, and the performances are excellent compared even with recent same wide angle lenses. Color, sharpness, correction of distortions and aberrations, vignetting and total solution capability is my favorite. So, this survival lens is one of my marvelous treasure even in Digital image period of time.

Leitz lens test would be performed today utilizing M9 M-mount body, also Minolta MD Rokkor 28/2 wide angle one would be carried together, the mounting adapter was prepared by combine M-body cap and MD lens cap together establishing flange back distance. Though range finder coupling mechanism does not exist in the adapter, distance measuring is done by reading the descriptions on the helicoid ring, as actual metering is not performed, the deeper focusing on wider angle lens would compensate an inconvenience enough to finish a desired transparencies. As for Elmarit 90/2,8 carrying together today has 90mm length of cylinder design, so lens designing is not some Tele-Photo one like nowadays construction but with a conventional long cylinder. All the Leica-M 90mm lenses were experienced by my actual experiment, the first generation model of Elmarit 90/2,8 remained at my hand now. Shorter and newer designing are not always exceedingly better than former model.
I have some sense of discomfort on Tele-Photo, Aspherical and Apo designing, that cannot be describe in words.

A small piece of pamphlet here reminds me of a fantastic work of perfect concert the day before yesterday held by Ashiya Symphony Orchestra at Fukushima OSAKA. I must put an emphasis on the point that incredibly unusual super orchestra sounds were discerned compared with unlike playing until that evening, every specific sound was heard independently in the condition that instrument was cleanly separated under no loosing the ultimate balance of harmony. Among them, the fullness and thickness of the strings were above words. No tiredness nor boring were felt through all the programs for 2 hours.
The reason was change of conductors into Mr. Sachio Fujioka who is also a conductor of background music of NHK Big Stream Drama "Kiyomori Taira". His way of music expression is balanced at the moment to feel harshness, so splendored as to keep all the audience keep on seats without taking napping a little.

An articulation of violin, viola and cello that were supported by bass sounds sounded so happy taking them in the center of my spinal cord leading to being in my deepest pleasure, I would not be taken them for my lifetime away. What I just ask to a symphony orchestra was the sound to had been played at Fukushima Osaka the other day!
I got some information about the specific string play from a member as one of a base instrument player that there was some inquiry by a new conductor, "All the string phrase should be done with emphasis and much stronger than before, otherwise the audience would fall asleep in long duration." Probably this is the reason for a remarkable improvement of the quality as a established Symphony Orchestra. As a matter of fact that I felt I would like to come for the same concert again, this is a good proof that the team playing quality as a professional has a sufficient, though all the member are formed with amateur persons.
Also, I was much fascinated by a marvelous artistic movement of arm muscles, Deltoideus and Biceps branch2 of violin concert master woman situated just in front of me.

The steering stability on VW 1302 Super Beetle during both in straight running and in turning curve has remarkably improved as to be leveled with recent automobiles, especially over steering phase is easy to produce by throttle controlling leading to comfortable cruising. This marvelous change was brought only by some modification on the rear trailing arm inner bush to preventing lateral displacement of trailing arm and rear axle construction. We might pay attention to only on frontal steering linkage and it supporting construction when any inconvenience are found on steering reaction, but remember here that the rear axle construction especially to lateral direction has most to do with some strange and bad feeling phenomena. The signal in-put on steering wheel is consumed by the lateral displacement of deformable rear axle construction, this is why the dull,muddy and sticky are perceived by the driver as no action with dead band, initial rising stage has no action till coming to surrender of deformable bushes finish in the construction. So, the prevention of lateral displacement of rear axle construction is very important to establish some astringent steering reaction.
I must make it clear that my intention to modify my Beetle is not arrange the original condition to pull up potentials, but re-acquire the performance of original design, because I love and admire the VW engineer's concepts 40 years ago, if they might have gone.

By the way, recent A segment smaller and low price passenger cars invite torsion beam axle, so they have disadvantages on this point, because their rear axles are so made to distort innately. This opinion is based on my actual experiments tried on EP82 TOYOTA Starlet and BLE SUBARU B4 3L model, though the axle constructions are different, former was rigid and the latter was independent promptly, the results were exactly the same, too much compliance resisting lateral force invited dull steering reactions. The attempt also on Super Beetle has carried out and established the same result as usual. Even small piece of rubber sheets could have brought a great achievement on 40 years VW 1302 Super Beetle.
