OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Breather Tube

Hi guys. I recently broke off the breather tube on my 5hp Briggs Quantum and can't find where I put it. Can anyone tell me how important it is and if it will effect the performance if not replaced. I can't justify spending $40 on a piece of tubing 3 inches long.
Thanks

use any tobe that fits, gardenhose, etc

They are a bit of a bitch design and difficult to use a piece of tube. Depending on where in Melb you are I have some here you can have.

Just thought I'd post a picture of what has broken off. Not sure if a piece of garden hose will work. Guessing it's 5 to 10 mm in diameter. Can anyone tell me what function of the breather tube is. ie, what's it for?

Hi Dave,
That is the breather tube, takes crankcase gases back to the carby inlet so they ban be burnt. It is needed to maintain negative crank pressure otherwise motors will pump oil out at every joint. Plenty of those here if you want one
