I believe you but I also know a couple ppl (myself included for a few months before my swap) with stock KA's and walbro pumps and their cars don't run shit rich as the OP is describing, maybe they're just lucky..
I have a hydraulic pressure gauge and when I hooked it up after getting my swap running the fuel pressure was proper @ 43psi iirc. If an sr is supposed to suffer the same problem with a walbro then i guess i'm one of the lucky ones too?
