I picked up an a Exponent liquid fuel stove NIB a few months ago.  It lights up fine but I cannot get this stove to simmer.  It’s either full blast or off.  Any help??   TIA

First, I don't have that stove so can't be of much help, but did you try running with lower pressure to see if it behaves better for you?

Is your Exponent a 442, 445A or 550B, or other?

Some of these can be very finicky. Pull the generator off and make sure the cleaning wire is attached to the E Block. It works just like the cleaning rod in a lantern generator. It also controls the flame height on these little stoves. I have a 440 that works the same as the 442. It is very touchy to get it to simmer. I have other 442's that are not touchy and you can find the simmer without any problems.

I've seen this same issued with a 533 also.  Was unable to figure it out.  Changed out the genny and fuel tube/Schrader, but no luck.  Finally punted on this one.

My feather 442 is either a flamethrower or a fireball, not my favorite stove but great for coffee. If you want simmer look for something with a second control thingy like a 400A or a much older stove like a 500A or 502.

442 stoves in my opinion need really high pressure to avoid flooding, I wouldn't run mine without pumping it till my thumb hurt unless I had a fire extinguisher nearby.

Mikew,
I agree on the 533 stove that it does not really simmer. i have one and I just thought thats the way they are. I am not sure about the exponent but I am given to believe that the most of the Coleman single burners are not good at simmering.

Not a fan of 442's here so - whatever Paul says sounds good to me. The older Coleman Exponent Apex II is a very good simmering stove but has the split tank/burner, more for backpacking.  

I use a 500 Speed Master or 550b when I want a single that simmer's on command.

Have had 3 of the 533s and only one of them works as advertised.  As far as most the Coleman single burners not good at simmering, I think it depends on the model.  I have about 7 of the 502s that were in various states of condition when I got them and all of them simmer very well.  Both of my 500s do also.   Maybe it's just me, but it seems that the simmering issue is more susceptible to the schrader valve models.

This is a shot in the dark.  The generator/valve on these is basically the lever that turns it on and off attached to a wire that has a pricker on the end that will "regulate" the output using the wire and orifice in the end of the generator.  Setting these are finicky as any perceptible adjustment from your hand is too much.  The 4A iron is just like this.  It uses the 604-299 generator which is essentially a skinny R55 generator.  The instructions for these told the user to adjust the flame by tapping the cleaning lever on the generator with the handle of a butter knife.  It sounds goofy but it works.  Light taps on the handle will allow you to sneak up on a low setting.  Perhaps this technique would work on these stoves.

That's funny Dan. I hadn't seen that before but for sure I've made many a lantern run at reduced flame by accident - tapping on the cleaner assy with a wrench, ha. Don't know why a butter knife wouldn't do the job as well.

I've had a few 400b and 442 stoves that did the same thing. What I found was that the brass end of the pricker wire was not in the valve properly. Once I fixed this all of them simmered fantastically.
