LT2000 w/Honda GXV530

Hi,
just wonder if any here has the above yard tractor and experience with that particular weird carburetor.
Q1: What is the settings for those two prime jets, that weirdly has to be bored out and replaced?
Q2: Torque specs for the whole engine (link?) especially the 4 fasten bolts for the carburetor?
Thanks!

Going to need the engine's serial number and spec number to even look up the engine.

From Owners manual IPL the engine is a GXV530-EXA2. Four different carbs used depending on the serial number of the engine.

All I see as adjustable screws is the idle mixture pilot screws. Typically they are set at 1-1/2 turn from seated position as an initial adjustment.

Thanks!
Those two have these blockers and must be bored out. Once out, I got new jets and set them between 1 and 2 turns out - without significant different on the engine running.
But, the choke is running up and down, that automatic (!), but its ON to compensate - for lack of gas?
The whole fuel system from tank through carburetor has been cleaned with new gaskets.
I suspect that the fuel pump could starve the gas/fuel flow.
Quite a bit of challenge. Thanks again for follow up!
