275A has huge flames while warming up, playing with the on-off knob it is hard to regulate the fuel flow.
After a minute it warms up and burns nice.
I have seen the diagrams for lanterns that have a "light" knob position, and understand how that works.   How does the 275A accomplish this?

Anyone have a diagram, and know where to look to diagnose the start-up circuit?

Cheers.

I don't have one of those lanterns, but I think the general rule (and probably operating instruction) is to fully open the fuel valve, light the lantern, and don't mess with the fuel valve until the lantern has heated up and is burning strong. The design has differences from the earlier 1/4 turn to light lanterns. The below patent pdf file probably has what you are looking for as to operation.

You can light almost any Coleman lantern with flare up at start - just throttle the fuel valve. Shut it down until the flame dies a bit, open, close, repeat until it is running as designed. Imperfect but it works. 

Yes, often there is a mechanical, verdigris, particles, or fuel varnishing reason they flare up whether they have a Shrader or old school F/A still the above method works for all - if you're okay with a little drama.

Agree with Chuck.  And flaring is a real good reason to only light up GPAs outside.

I was under the impression on the 275s , add fire to the mantles first then turn the valve open to ignite.

yup my most recent 275 does that. It lights easy but I have to shut it off to clear the flood when it is 1st lit. let it almost die then turn the valve back on and it runs fine. My other 275 doesn't do that. 
Strange because the one that does flare, my Dad bought new "back then" got used 2x maybe 3x then hung in the garage and collected dust for over 30 years, I think I fired that one up once in the late 80s was the last time it was lit before a week ago. that one is a 10/81. 
the 275 that I haven't had long (couple years maybe?) and is a 6/81 and I cant remember where I got from (probably auction or garage sale) gives me absolutely NO problems. 
Related.... how do I tell if it is a 275 or a 275A? is there any difference between them?

The 275 has a "LIGHT" position on the label behind the knob and on the instructions on the collar and also a detent to stop the valve at the light position as shown here:
275_Valve_Stem_Index_2.jpg 

The 275A does not have a "LIGHT" position and the instructions on the collar tell the user to turn to ON position to light. At least that's the case with my 275 and 275A. I suspect that the 275 may be using the newer style plastic F/A tube instead of the brass type, but I don't know for sure. 

Also, the ICCC site shows the 275 from 1976-1979 and 275A from 1980-1983. (http://intlccc.net/information/modelyear-reference/by-model/).

I haven't disassembled my 275A, yet, but you can see my disassembled 275 parts here if that helps: https://sklcolorado.wordpress.com/2018/12/17/coleman-275-lantern/

I lite mine with low pressure 5-10 pumps. Add pressure when running as it should.

If the lantern has the brass fuel pickup tube (check thru the fuel fill hole with a flashlight as one may be able to see it), per the patent drawings it should have a "light" position. These lanterns have a fuel control rod similar to the 1/4 turn to light lanterns but it moves down instead of up when put in the "run" position. If you look at the diagram of the fuel pickup assembly, the fuel control rod has a skinny section just before the normal sized tip. In the light position the normal sized tip is in the fuel pickup orifice similar to the earlier lanterns for starting. When the fuel control valve is placed in the "run" position, the fuel control rod moves down putting the skinny section of the fuel control rod in the fuel pickup orifice allowing more fuel to flow into the fuel pickup tube. If the lantern has a plastic fuel pickup tube, then that is "different".

I take off the vent and globe from my 275 when I light up.

This avoids soot on the vent and globe.

I replace them after the flair-up at starting.

I do this with the NorthStar lantern too.

This works! Thanks Daveofswm.  5 pumps on a full tank and it fires up without drama.

Also this is a much better way to throttle, the schrader ON-OFF valve is really touchy on this model. 
I may grow to like this Turd, once I get used to its quirks.

I tried to follow Coleman's lighting instructions to the T, the thing burned with blue/orange flames for ~30 seconds before finally igniting the mantles and settling down.

I wonder if the lack of oxygen at my altitude of 7400 feet makes the mixture richer than needed.

The 275A number printed on the collar, It doesn't have the "Light" position on the knob.
My 275A was bought new by my Dad, and had been hanging in his basement collecting dust for 30 years, always had my eye on it, and now it's mine😁

I live at 6840 ft and lit my 275 two nights ago without drama, so it doesn't seem that oxygen at elevation is the culprit.

Have you checked the Schrader valve operation by: pumping 2x-3x the normal pump cycles and then letting it sit for 30 minutes to see if any fuel is dripping down the generator?

Have you cleaned the generator?
