Bongo Fury

After a damp night my bongo Mis-fires and white smoke comes out the back end, I had the glow plugs checked and they are fine any thoughts.

S Jacobs (worried bongo owner)

Engine/pump timing out, Fuel starvation to the pump causing the pumps timing not to operate correctly, Low engine compression Water/petrol in the fuel

I just saw the "damp night" bit...Most likely condensation evaporating out of the exhaust...So that'll be steam most probably...Nothing to worry about if the "smoke" diussapears when your bongo has warmed up a bit...

It's classic symptoms of glow plug failure. Did they just test them for continuity of the circuit? If so, they may not be heating properly and there have been a few nippy mornings lately. Does it clear quickly after starting?

I'd disregarded dodgy plugs as Mr Jacobs never mentioned having trouble starting the bongo john... I've only had to have my plugs replaced just the once, i never noticed the white smoke/steam issue when "they were on their way out" All i noticed was a stumble at first, then longer and longer cranks starting when cold, they do seem to fail quite quickly though, they did in my case..

Anybody's guess Ste I was just wondering if the damp mornings were also colder and the white smoke was unburnt fuel, due to the misfire. I had an old Fiat Uno that started instantly but misfired and smoked for a few seconds. I checked the glow plugs for continuity and they appeared fine, but when I removed them, it was obvious that three of them weren't getting up to full temperature - new plugs sorted it
