its not a fast carb, but this question is pretty quick: I'm disassembling the carb right now, and I've got it down to the last thing. That would be the large needle. I can't get it out of the cylinder. Unless I'm mistaken there is a flathead screw down the small diam tube that will release it, yes? Is my screw just real tight? Or: how do I get the needle out? Thanks-- J oh, yea.. this is a stock Bing CV off a '90 PD. thx.
