Not sure I understand how it's going to "pop" 1/4 in. You mean off the far (open) end of the bend ? There's not a lot of play on the rod, I thought the carb would slide off toward the engine.
Sorry if I'm being a bonehead.
Let it soak overnight with WD 40 or even better PB blaster. Those bushings get hard and crumbly. Pop the rod out of the carb not the carb off the rod. It only pops out like 1/4” and it’s free!
