The hose i believe you are talking about is the carb drain hose it is for when you drain the carb it wont run gas all over your motor, some have a screw in the end some have it up on the carb bowl it should not effect how the scooter runs if gas isnt running out of it.

This scooter come shipped with shipping oil in them and needs to be replaced on arrival that could be some of the issue with the noise but beside that it needs to be replaced not sure what size the cable is but error on the longer side because it will work no matter how much longer it is but will not work if it is to short i am going to give you some links, its a 50cc scooter he is using but it is basically the same thing has your motor some small differences first is a pdi video that has 10 parts to it and a second for changing your oil this guy has alot of good videos of how tos and he is very knowledgeable and has very good videos, you can learn a lot from him, i have.

The carb might be sealed so that would be a issue also you would have to deal with when installing a bbk tuning the cvt helps a lot also, you are not going to gain more power but be able to use the power that you already have better.First thing i always do is add lighter rollers to any scooter that i buy, makes the motor more peppier and throttle response quicker imo the weights are way to heavy that come stock
If your scooter was a 64mm valve and installed a 69mm valve head with bbk or vice versa you can cause a bent valve with the wrong rocker arms There are short and long rocker arms one for the 64mm and one for the 69 they wont work right for each other, if you put your stock head back on with the stock rocker arms should work fine after
I have ran the stock 17 on bbk and a bigger 21 mm carb, the aftermarket bigger carb will rev faster and respond quicker but you can run the stock with about has good results until you can get one.I do recommend to by a jet kit for whatever carb you buy cause you run a on a stock doesnt mean thazt will be the size you need in the new carb plus it handy to have the extra sizes around for different season or if you change to a different filter later or so on
My 70cc 2t has no problem dogging the stock 150 and i have beat the zuma 125.I like the steel kits better with duel ring for everyday riding and longevity but must aluminium kits are made to produce more power and can last and be used for everyday riding also but most are single ring kits and will need to be rebuild sooner then most steel kits plus if you every soft seize most aluminium kits are shot after one. my favorite steek kit to date is the stage 6 street race. I have mixed gas manually and used the pump i prefer the oil pump much better,simpler and i think you use less oil that way. I live in va and have a lot of mountain in my town no issues on the 70cc there but having a properly tune cvt is also a big key on any scooter to get the best results from your scooter.
