Can a 220 jet be used in a mil spec lantern. Just need verification. Thanks

Do you mean swapping the generator tip?

If yes, looking at the charts the MilSpec appears to be a tiny 0.0045" while the 220 is 0.008" so you might be getting way to much fuel?

A 220 tip (.008) seems like it would flood the house and yard.  Remember, there's normally a pricker needle in the way of full flow through that orifice.. a 200 let at .006 would be a lot more likely to play, and even then your world will have an orange tinge.

Reading the tread Smudge posted I think I'll try a 200a tip to see how it does. That is after I buy one I'll have to check if OCP has one. Too bad I just placed an order 2 days ago.

The .0045 size is incorrect. the wire that that would be used for cleaning that would be way to flimsy. No a #6 tip from a 200A is a direct replacement. no need to have both air tubes open, unless one is actually blocked by a bug...

 0.0045" is NOT incorrect.  This is correct for examples I had on hand when these tips were gauged all were NOS Coleman manufactiure still in the packaging 6 tips were checked 3 from gens and 3 replacements all NOS never installed.. A 0.005" gauge would NOT pass the through the gen tip on any of them and the 0.004" gauge was sloppy.
 
The the diameter of the tip from other manufactures may be of a different diameter and orifice design to achieve equivalent flow rates . 
The diameter of the is not the only thing affecting flow rate  but length of the orifice and profile will also affect flow rate.

Milspec tips are prone to erosion and it does not take much running time to erode them. 

The milspec's I have played with were not that bright and often were quite dim.  I messed with tip swaps on the Mil spec over a decade ago and the best results were with the #6 0.007" tip uncorking the other tube and using a 99 Mantle and shortening the burner tube to get the mantle up away from the fuel valve out let. 

That swap resulted in an easy to light stable, odorless and very bright milspec, albeit rather loud. 

There was a rather detailed write up on the Old Coleman Lantern Yahoo group, that now that seems to be MIA , ashame really as there was piles of information archived there.

Matthew, did you ever mic the tip cleaner wires that came with those Mil-Specs? I've never had a dim mil-spec... They've all been as bright as or brighter than 242s/200As...

 Can't recall the size think it is was 0.004 or there about's if I recall correctly. 

The early mil specs were dim there were several threads about it on the old Yahoo group.  At that time the 1980's era SMP units were basically non existent and were just starting to be surplussed off.  I suspect the early lanterns were designed to be used with the higher calorific gasoline of the era  So they would have to had have smaller gas tips, run on Coleman fuel they were dim. 
Just swapping the tip to #6 tip resulted in a yellow mantle with the stench of running way to rich and and almost flames on the out side of the mantle, uncorking the air tube made it much brighter but with a fairly big halo. The 99 mantle solved that but it was pretty close to the fuel out let swapping it for shorter burner tube solved that that. 

That modded Mil spec (1952 Coleman production) was an excellent running lantern, it took what was basically a pig of a unit and made it in to first class lantern and one of the best running and lighting I had in the collection at the time.

Thanks for your work and the history that went with it. I had my own opinions of orifices and the many iterations of the Milspec and you've cleared some things up. Thanks again.

I put a 226 tip on one of my Mil-Spec lanterns and did not notice much of a difference.  Maybe I'll try the 200 tip.  I only have two working Mil-Spec lanterns and I don't think either of them are very bright. Maybe I'll try the 200 tip and see if that gets one of them brighter.

I went through this myself and found that the 220 tip at .008 is a bit much.
the 200a/242 tip for CF at.007 works IF you open both tubes.
the 201 tip at .006 works well as is IF the position of the tip is in the sweet spot of the mixing chamber, but works nicely also when both air tubes are open and is a bit more forgiving.
