honda gx390 black smoke

[Ant-h83]

Hi all, I have a predator 360 that runs fine until I tilt it to grind and it starts smoking out of the exhaust, being black smoke I assumed it was overfuelling and it doesn't like to tick over either but it does smell similar to oil burning, is it new engine time or a simple fix? iv changed the air filter and its still the same. any advice is more than welcome!

thanks.

Take it to someone who knows what they are doing on Honda 4 strokes ....

Black smoke would suggest it’s rich, possible blocked air filter, has the engine been excessively tipped up? Is there oil in the filter? Carb flooding, I believe it has an internally vented carb, so leakage sends fuel into the engine via the inlet valve,

If it's fine until you tilt it then I'd be thinking the float is sticky or the needle is leaking. Pop the bowl off and clean it all out. Make sure the float doesn't have anything in it and clean the needle up! 

 

Double check the oil level too.
