Glad to hear you got it set up right. I don't know what carb mine has but it runs fine. I drilled 2 half inch holes in the plate that divides the muffler chambers, and then added a 288 screen and outlet on the primary (closest to the exhaust port) muffler chamber, with 1/2" hole, welded the outlet and screws, it barks nicely now, is USFS legal, and with another 1 1/4 twists on the HS fuel screw it rips.
I bet if you open the muffler, combined with the porting you will have a smile on your face. Good job.
