Default Carb Q

My son bought this for his GX200. After he installed everything there really wasn't a noticable difference over the stock parts. Does the bigger jet and different emulsion tube require the air/fuel mixture screw to be adjusted in order to see some performance improvement?

Yes, I'd expect you'd need to re-adjust the mixture screw, although it only/mostly affects idle and just off-idle.

Have you made any other mods to the engine, specifically for reaching higher than stock rpm? I also wouldn't expect to see a gigantic improvement with those parts until the engine revs up above 3-4K and higher. At lower rpm the stock intake and exhaust aren't much of a restriction, and header pipes need some rpm to be really effective.

Don't get me wrong - those parts will definitely help, but just not hugely all by themselves.

Thx for your reply. The motor is all stock now with the exception of the parts above. He wants to remove the governor and install stiffer valve springs next.

OK, then you'll notice a difference. Well, not really a difference unless you put the stock intake / exhaust back on and then try to rev it higher...but that would be silly!

Anyways, if you haven't already, be sure to check out the "Governor Removal Reality Check" thread here: http://www.diygokarts.com/vb/showthread.php?t=16518

Have fun!

Governor yes, valve springs, not before you upgrade the internals...
