I was disappointed to know that OS does not supply the part of 7DV carburetor spray bar any longer because of old model. As I have been suffering from stuck feeling at the fuel squeezing construction from new condition. This strange phenomena should be caused by some low manufacturing(poor quality control) by the manufacturer. So, I tried to establish the centrality of spray bar inclination by inserting metal rod inside, applied stress damaged splay bar slit portion by chance and incredible breakage happened along through the slit miserably as a matter of fact, Oh my God! Fuel squeezing mechanism in 7DV carburetor has lost completely, how come? The carburetor should be brought to OS service front asking any countermeasure before I did poor action on it, then they must have done well with it as usual.

This destroyed part had been thrown away for long time because of the reason.
Just I imagined the way to rescue this lonely one by myself imitating the fuel passing ways in YS 60 FR motor, yes, engrave the sharp triangle passing way on the throttle valve and carburetor body inside. Deeper consideration should lead me to do that because have I a good control in front of me. Several precise modifications must be required on the way of machining procedure, but I'll do that once the idea comes in to my mind.
Wanna I fulfill my ambition, it is interesting, don't you think? Of course OS 61 RF rear exhaust port type motor would be operated in combination with YS fuel pressurizing regulator system.
Reporting on this interesting trial attempt would be done later.

As I felt some strange feel at the state just before stop, inspected I front wheels of
Super Beetle by lifting up, then unacceptable rotational resistance was observed in right side wheel, so to speak stuck feeling.
Following the natural countermeasure for this inconvenience, the brake drum was removed, no problem was found out in wheel bearings, inner and outer.
Careful checking on the operative cylinder, the sliding pusher for the trailing side was cohesively stuck. This kind of banish like material might have come from gradual leak of brake fluid or denaturing of silicon grease applied at assembling stage.
Removing all the banish there and reassembling the construction re-obtained the natural function again.
Whenever we start the brake maintenance work, some dust sheet under the wheel must be prepared, otherwise, the pit floor would be spoiled as shown in the picture.
I felt the necessity to check brake construction periodically, the maintenance sheet by the constructors is not always prepared unreasonably.
