You can never tell. Some I buy come with a #80 jet..some come with a #85. sadly most of the stock carbs that come on Scoots are #72..#74 and #76. Which is too lean for most folks. As to what jet you need..well it all depends on your elevation and environment. Always start rich then go down in size until you have it running well and the spark plug is a nice caramel brown. Too lean and the plug will be ashen grey to white..which is dangerously lean. But as most here know by experience..TaoTao ships scoots with the carbs set lean to pass emissions testing. But what ends up happening is it burns up the piston.
Jets are cheap..so just a wild guess to put you in the ballpark you could try a #82 if the engine is stock(no big bore kit) You may not need a jet kit..unless in the future you plan on adding a big bore kit..performance pipe or free flow air filter. Adding those will require you to change jetting..but that is not a difficult thing to do. In fact it is part of the fun that we folks here have in tinkering with these lil 50cc Scoots..cause nothing makes ya prouder than a well performing properly tuned Scoot..vice the out of the crate turtles we buy them as..
