More like #90 main jet

Stock 50cc a 17 mm bing came with a # 84 jet.

You probably have a airleak for using janky ass tape on your intake. Luckily for you it won't run cause if it did you would have blown up that kit.

Get a intake that fits, problem solved.

so its just a big air leak?

Probably. Throw in a bigger jet like Roff said, won't hurt to try. Make sure to check for airleaks before you open up the throttle on it though.

Spray around the mating surfaces with some carb cleaner. If you have a leak you will notice the RPMs drop.

yeah i had a 90 jet in it before and it didnt move at all then haha

Re: my maxi wont GO!

is your carb a 17mm sha or a phgb?

phgb has idle and choke jets.

Re: my maxi wont GO!

ive had troubles with that k-star cylinder and carbs smaller than 19mm, but we i also opened it up a bit more. its also really common for that particular kit to have air leaks

^ Especially when you use tape to get your carb on your intake.
