So I go to a small engine parts website and put my engine Model and Type (286707-4029-01) in to order, new imulsion tube. I click on the Carburetor drawing and it brings up a page of exploded parts drawings that include a Nikki at the top and a Walbro at the bottom. The walbro has a 125 in the upper left corner that I select. And that opens a window that shows options for "Gravity Feed" and "Pump Feed" with "Gravity Feed Part # 498027 Unavailable" selected. The window shows exploded drawings for Nikki at the top and Walbro at the bottom. I choose the Carburetor Nozzle (# 142) and a window opens up showing a list of LMT and #'s to select from.
When I select one by clicking to fill the dot, then the nozzle Part# and availability is shown.
I assume that my origional Walbro carb is the B&S # 498027. I don't see any such number on the carb. Which LMT do I select based on what I find on the carb that I have in hand? The following pictures are all of the numbers that are found on the carb.


Thanks for your help!
