288 and 285 question

#1

Post by Jayhawksr »

I’m camping at the lake with the boys and told a buddy I would fix his lanterns. We are looking at a 288 and 285 both running white gas. The issue is a lot flame at the mantles even after the genny is warmed up. It’s almost like a fuel and air aren’t mixing right and its fuel rich. Any suggestions would be great. I don’t have much experience working on the newer models but I did bring a good selection of tools.

"I don’t have much experience working on the newer models but I did bring a good selection of tools."

These types of lanterns have a different method of startup and operation than the older lanterns, so it is important to understand how they work. The first thing to note is that they need to have the fuel control valve full open to properly start. Less than full open may result in flooding and a fire ball. I suspect they are not being started properly since both lanterns have the same issue. What is your starting method?

I am following the start up procedure and I have a fully functional 288 at home. Where i am at now is it still why I’m getting g flame up after startup when the fuel should be fully vaporized.

Ok. Next, how long did you let the lanterns run to see if they would start operating correctly? It may take a minuet or two to clear a flooded condition. After the lanterns have operated in the degraded condition, have you tried throttling back the lanterns using the fuel control valve? If so, did the output change? If the output did change, did the lanterns have aa "sweet spot" where the lanterns appeared to be operating better?

How long do the minuets need to be? What if he doesn’t have any to listen to at the campground?

But I like to dance when I get a lantern lit.

And more seriously if the problematic lanterns were stored for a long time they might have blockage in the air tubes.
