I've got a QL lantern with Q99 generator that seems to be getting too much fuel.  There are flames outside the mantles (I'm using 21A's) that leave black carbon deposits on the mantles.  I've cleaned the gas tubes well so I'm pretty sure it's not a lack of air.  After searching the forums it seems one possibility is that the gas tip on my generator is oversized.  Does anyone know where I can get a replacement?  I searched OCP and they only seem to have the complete generators.

Is there anything else I should check for the overfueling problem?  I've tried experimenting with the pressure and while the problem does get worse the more pressure I put in, it never goes away entirely, even with just 5-6 pumps.  Any help would be appreciated!

Thats good to know Steve.  Check the tip under a magnifying glass.  If it has a I on it it is for an iron and dumps more fuel than normal.  Others have said the oriface actually wears but I just cant see that happening.

I tried the generator tip from an old 220 I had laying around and it definitely seems to help.  I'll have to try it out tonight when it gets dark so I can see any halo better.  I just pumped it 7-8 times.

I also read on the forum that obstructions to the burner screens can cause haloing.  I've cleaned my burner screens, but I did notice that each burner had two screens, one on top of the other.  They were 45 degrees out of phase with each other, which had the effect of making the openings half the size they would be if you just had one screen.  Is this normal?  The fact they were put together so precisely tells me it was done on purpose, but I have no idea if it came from the factory like that or if an owner modified it.

My experience with lamps have ben a bit different. When I had the haloing problem more air pressure solved the problem. Hand held pump wasn't doing it so I gave it a 4 second blast from my pancake air compressor and it ran like a champ.

Some were designed to use two screens.

Most have the double crossed screens as you describe. 

The generator tip swap should work along with more pressure. How do tips get enlarged?  Often by previous owners using wires or sewing needles to prick them instead of the proper device.

The 220 gas tip seemed to do the trick - no signs of haloing or overburning.  Thanks for all the advice here!

To your point Greg, I have another Q99 generator that came on a junker Quick-lite I found a while back.  The hole in the gas tip was visibly larger than the one on my good lantern and there was even metal pushed up around the hole - someone must have reamed it good!  I tried it just for kicks and it flared up badly.  Someone really did a job on that generator at some point.

I'm glad to hear that you got it going again!

Air tube restrictions can be difficult to clear. Many of the critters that build nests in these use materials that don't particularly dissolve in water. Physically running something like a frayed-out stranded wire through them is usually the best method.
