Float Height for 30 S2 HR, BIS Carburetta ?

[andyzeetec]

Pls help, I'm after the float heights, x and y for the 30-S2 HR polish carb for my BIS

Odly the data sheet that came with the service kit doesnt include the info for the kit in the box, which is about as much use as a chocolate fireguard.

The current float heights are 3mm and 16mm

 

The kit # is K789 which is not listed in the pic below

Got an answer from Axel Gerstl....for reference for anyone else that might need this info..

"thank you for your eMail. Unfortunately we have no exact details but it should be X= 6 mm and Y= 13 mm."

As the 30S2Hr is a polish copy of the Weber 30DGF, it sort of makes sense, so I'll get adjusting those float tabs.

Got it all back together and started great, although still difficult starting when hot,(need to put my foot to the floor on the accel pedal for it to catch and fire up)
So I am just wondering if there is anything that will improve starting hot or needs setting up. With the carb service kit I also changed the diaphrams (pump & fast idle)and not sure how to test or setup the fast idle. I guess the lever should pull down when the fan kicks in, and up’s the revs?
Also does anyone know what the circular unit is on the other side of the carb with the plunger coming out the side powered by vacuum?
Trouble is the workshop manual is geared around the webber, not the polski
