Arreche 821/16 or 819/16 diagram

[SactoScoot]

Hi Guys,
I just got my new special order 21mm carb from Provo and I got no idea which plug is the oil hookup. Is it under the white or the black plastic plug? I did not get a diagram with the carb or the extra jet, both which came with the 19mm one I bought three years ago. Of course, I lost the parts list/exploded view drawing which shipped with the 19mm carb... Does anyone have a diagram for either the 21mm or 19 mm auto choke and oil injection model?

Btw. The company's website, www.arreche.es, blows... Nothing on it!!!!

Thank you in advance...

Take caps off, smallest plug will be the oil hookup. It's easy to distinguish because it looks like a small spigot. vacuum plug will be slightly larger and directly coming from the carb usually farthest line to the back of carb. Fuel line will be biggest and closer to the front of carb.

Take a pic of carb and I'll identify the lines for you for sure.

Thank you!

Also noticed, that the smaller white plastic covered nipple, which is closer to the body and horizontal, has two "bumps" on it, while the further away larger black plastic covered nipple, sitting closer to the back almost vertical, has just one "bump".

right, horizontal and two bumps should be your oil. vertical, vacuum.
