HD-17D - mystery jet

[duckmansweb]

Hi guys - can someone enlighten me as to what the jet next to the welsh plug that has “34” stamped into it does? It’s not listed in the parts list - the other two jets are self explanatory.

Looks like it feeds the L screw?
The one marked 66 is a fixed jet that always feeds the H side. The hole between the jets probably feeds the H screw

Probably not listed if its non serviceable

Here is the walbro blowup.

It looks like a check valve but with that number on it, it is probably a calibrated orifice that feeds fuel to the low speed circuit and the #34 indicates the size of the orifice.

I prefer my orifices "calibrated".......
