Hi all,

I have a Briggs & Stratton 5HP (Model Series 124800) which needs a work, but still runs. It is blowing black smoke. I am tying to rectify this by cleaning the carbon build up on the head, adjusting carb, new air filter etc.

I have noticed there is excessive oil in the air cleaner box. It is coming from the breather assembly tube. I have not disassembled the breather assembly to investigate, however does anybody know if this a symptom of something seriously, or if it is a easy fix.

Thanks in advance.

Regards
CC
