It may just need an adjustment with the needles.

 

[slyme]

how do I do that?

There are screws on the carb that you can play with. You will have to check a manual.

Make sure gas is coming to the carb. Also, maybe your float is not working correctly in the carb.

So, before adjusting the carb, check that gas is going to the carb and that the bowl is placed correctly.

ok.
