hello their opera's,
question?
1. anyone can tell me the 'rebuild kit model,' necessary for this one?
(see pics) 1-3
2. any person know what the part is called in pic 4-5 ? (it inserts into the hole its next to, same exact size as the plug cover outta the rebuild kit to replace a screen filter, but obviously it wasn't one) appreciate any suggestions, (and yes I know 'tillotson has a support size, no, I havn't tried em.)

Thats a HS172 carb. Off a Partner P100 maybe?

I don't know why so many HS carbs didn't get the H stamped on them.

Your kit you need should be a RK-23HS kit.

The thing your asking about is your main nozzle check valve.
