Hello,
Any time you change inlet or exit flows on an engine that is metered with a carburetor you have to adjust fuel scheduling.
When you install the "baffle" try and adjust the fuel air screw in 1/2 turn [ CW direction ]. That adjustment will lean the start and idle fuel schedule and may get you going. But anytime you are backing up the exit pressures with a baffle you should lean the main jet & change the pilot jet. That is if you cannot get enough adjustment from the AF screw to compensate the start / idle circuit.
Hope that helps.
