I need help with my fiat 600

Hello guys, I tell you that I am assembling a Fiat 600, but I need some things to continue, that they are the Seat 850 carburetor manual and its measures; And the engine lubrication system in case someone has it, thanks before hand ...

Look here is the Argentine 600 r manual, which is the carburetor you are looking for, but beware of the crankshaft that is from right to left, that is, anti -schedule if you put the pistons on the other side, vs. to have problems 600 850 is also against clock turns from right to left, eye with the box also if it is an old 600 you have to turn the crown of the differential
