Light mods for the Coleman CT200U-EX

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.
I agree,, I’m going after the jet! I think I can get it

If I were you, I'd make it easy on myself, and just buy a new carb - It's cheap, it'll come with removable jets, an adjustable idle mix, and you can play around with tuning it to your heart's content.
As SAS289 implied, if you don't know what you're doing, you could easily just screw up the stock carb, trying to modify it.
I don't think it's worth wasting any time with it.
Gonna order a new carb too,
