FYI, I made 4 baffles by cutting plastic strips from a 1 gallon oil jug, I made a test pattern from a beer carton to match the cone shape of the filter ID. The curve matched the label on the oil jug so I traced out 4 curved strips that when rolled made a cone. They have a hole punched in each end piece so I can hook them for removal. They roll up and then open after they're in the pod, the strips tuck under the inside edge of the rubber so they're stuck in there. I tried to suck one out with my big shop vac and it stayed in place. They block about an inch of filter area, I assume a little air will flow between the baffle and the pleats of the filter too, then turn back toward the carb.
Anyway it was a good day for a test, it's about the same temp outside as before. We can argue the reason why, but it ran quite a bit better. It still needs some more midrange fuel but this is an improvement and it pulls like a kz should.
My thought is it straightens out the air flow near the front of the carbs and allows the air bleeds to see a little more vacuum signal. Everything should apply to a sohc with pods so use your own judgement. It cost nothing to try except a few oz of gas.
