Motorcycle Repair: leak, vacuum hose, mini motor

Question
Hello, I have a 47cc mini motor cycle single speed , ive only had for a couple of months and the vacum hose that runs from the carburature is leaking very rapidly after i shut off the enginebut there is no hole in the hose.can you tell me how to fix it? or what is wrong?

Answer
Hi Brant,

Vacuum works with engine running. I'm a bit confused when reading the description. If in doubt about the vacuum hose, replace it with new. If the problem persists, investigate further.

I don't know the year, brand, or model so looking up information on line was not an option for this reply. The description didn't include engine performance while running, etc... this is the best I can return with the info given.

Respectfully,
