I have a Husqvarna LGT2554 and am replacing the carburetor. Is there an easy to understand assembly guide for putting the throttle and choke components back together? Nothing in the owners manual or engine manual.

Hi,
You appear to have a Kohler SV730 engine and the service manual is at the link below:

And the fuel system is section 21.
Peace,
