Welcome to the forum.
Unfortunately I have not worked on one of the newer Overhead Valve Engines so I don't know if the carbs are the same as on the older Tecumseh's or not, but I do have one suggestion - Pictures and notes.
Before doing anything, start taking notes and pictures of everything before, during and after you touch anything. Something as small as hooking a throttle linkage in the wrong hole on reassembly can drive you crazy when it should work but doesn't (DAMHIK). If you have good sequential pictures and notes, you can always refer back to them to insure what is now is as it was when you started.
Get a manual and good luck. Let us know now it turns out.
