Some guys will do the work to get the jet out, while others hit the easy button and buy a new carb. I suspect that they are drilling the jet open larger then forcing a tool into it to unscrew it. If you try that make sure you don't drill in too far and ruin the e tube.
I don't think that the non adjustable idle is a big deal unless the RPM is too close to engaging the clutch. Other than starting engine warm up an idling engine is useless.
