I have a BME 102 Evo with the original carb on it. I
had a pushrod sticking out of the cowl so that i could
open and close the choke without using a servo or
cutting a large hole in the cowl. Anyway, the spring
got work out in the choke that locks the choke in the
open and closed positions. My local hardware store
might have it, but they need a part number, or some
better dimensions at least. Anyone know the part
number or some more description of the spring? thanks

I lost the spring out of my choke too and found the spring and the little detent ball at a local lawn mower shop. They had a bunch of old carbs from weed eaters. Give them a try.

I do not understand just what your looking for, post is not clear. But maybe a visit to the Walbro website site may help you locate the spring type and number.
