Did your kit come with new jets? I just rebuilt my 13877 Zenith and the kit didn't have jets which seemed really strange. I reused the old ones, and looked for new ones elsewhere, with no luck---seems they don't sell them...
No jets guess they cost to much to make and manufacture wants you to buy a new carburetor. My carburetor is running fine with old jets so far. Even if you brought a rebuild carburetor is probably using old jets.
