15hp 4 stroke -
Oily fuel smelling stuff dripping from air intake - from hose at top of block? The air intake box has a little hose running from the rear top up towards the rear of the engine and enters top of the block under flywheel cover...
When the engines fires with the hose removed from the airbox there's a blow back from that hose with dark looking oil that smells like fuel intermittently shooting out. Normally this will blow this fluid into the air intake box - through the carbs and into the cylinder/s.
The 2 attached pictures will give you the ideas of where the air box hose is, next picture where it comes from numbered 29.
Any ideas why that has happened? What the fix would be - or do i go get another engine?
Thank you for any help.
