This is fantastic as the pcitures tell a great story. Now if we could translate this into English, it would be even more helpful for this audience.

Thank you so much for documenting!

Sehr schoen beschrieben Herr Wartanian, und mit viel besser Deutsch als meins. Jetzt brauchen wir eine Beschreibung und ein angebot fuer eine billige methode um die drosselbohrungen auszubohren, zu "hard anodize," und neue drossellplatten zu drehen, Ich bezetze schon ein stab um die drossellplatten zu montieren und drehen, (7 grad wenn ich richtig errinere) und arbeite auch schon auf ein werkzeug fuer die bohrungen. In meine erfahrung mit zwei setze (schon) Man muss das normalerweise auch machen um die erwartete ergebnisse zu erreichen. Sie wohnen in NordCacalaci und ich in SudCacalaki - Aiken - eigentlich nur um die Ecke. Wieleicht sollen wir unsere Koepfe ueber ein Pils zusammen bringen?

Whew. What work. And if we really want to get serious, we should build a flow bench to leak check and calibrate the throttle bodies, and then (of course) we need a Sparky type from the forum (are you a Sparky type?) to help us rig the electronics to drive a 0-4000 rpm ~ 3 horse electric electric motor with a cog belt drive to start testing pumps....

Thank you Chip but I do not live anymore in the US. Currently I am in the country of no speed limit. I agree with some machinery we can rebuilds stacks from T to S. The hard part is the Drosselklappe Welle.

Never mind. Enjoy your beer.

Here an automatic translation by Yahoo

What a bull**** translation. Folks learn German.

Beer ordering while you are doing vacation is much easier that way.
