    It depends...is there a working steam pressure Guage on that boiler?   Can you give us some pictures from about 5 feet back and all the piping?   Mad Dog 🐕

    Settings look ok. Is that a steam vapor system?

    looks like you're cutting in at 3 psi, and out at 4,
    too high for residential steam,
    dial the left scale down to 1, or just under,
    you will cut in at 1, and out at 2,
    what's your gage show?

    post a more general picture, floor to ceiling showing the boiler, and connected piping above, and all controls and sightglass,

    Have you serviced the pigtail ?

    What about the 2nd pic??

    The second pic has an aquastat set to about 140° for domestic hot water purposes. Is there a tankless coil in the boiler?
    The other control with the valve is the low water cut off. You should run the boiler, then drain the boiler  through the LWCO valve while the burner is on to make sure it shuts off the burner when it reaches low level.
    Quid pro quo. Where's the pics?

    Yes it has a coil and it does shut off when I open the LWCO..  
    should the aquastat be left like at 140 ?? .. water is super hot especially when heat is on.. Also some mentioned Cleaning the pigtail.. but it doesn't have one..
    Thanks again

    When the boiler is steaming the water in the boiler is going to be a lot hotter than the aquastat setting. There should be a mixing valve on the dhw to keep it a a safe and constant temp.

    The aquastat is just a low limit to keep the boiler hot enough to make dhw when there isn't a call for domestic heating.

    That asbestos that is falling off is also an issue.

    Thatcher Furnace Company. So, a furnace company made boilers? Or did boilers used to be called furnaces?

    the scale on the right, that's your differential, leave it at 1,
    left scale is cut in, set to 1, the Ptrol turns boiler burner back on, (cut in), as pressure gets to or below 1psi,
    Ptrol shuts boiler off(cut out), at the addition of Cut In, and Differential,
    so,
    1 cut in, plus 1 differential = 2 cut out(burner off)

    the 1 on the gage, that's with boiler/burner off? for a while?

    you should add another gage,
    a lower pressure gage,
    and lucky you, I got an easy spot for you,
    there is a misplaced vent right next to your Ptrol,
    remove that, you don't vent air from steam boilers, at the boiler,
    add nipples and a ball valve, and top it with a brandsy new working gage, right there,

    and sinse your hooked,
    go to the store here, and buy,

    gage moved to the 2 position now..boiler off. it's been off for about an hour

    can you post a picture, more distant, of where that gage is,
    and of your sightglass,

    if you tap on that gage, does it jump around a bit?
    I wouldn't put a lot of trust in that old 30 psi gage,
    add another where the vent is,

    and I would unwire and remove your Ptrol, and check those nipples and 90 and into the tee to be sure that's all free breathing back into the boiler,
    take the Ptrol off and blow down into that assembly, it should be free breathing, or you need to clean and or replace those fittings,

    is the boiler off because the thermostat is satisfied?
    or,
    is the Ptrol not responding/restarting the boiler?

    Gage after running for about 45 minutes.  it hasn't reached the thermostat temperature yetbut it has turn off 2 times  and restarted. is that normal.  Turns on runs for about 10 minutes a d shuts.. radiators are hot.

    boogers,
    (1 ah sh!t = 10 atta boys)
    and I messed up,
    upon closer inspection, that does look like a safety valve,
    good call

    when the Ptrol nipps come apart,
    (because now we're at 6 psi, )
    an extra tee and nips can be added to allow for a secondary gage,

    would that cause it to keep coming on for like 5 minutes and turn off  its  done like 4 times..thermostat hasn't reached its point yet..

    The short answer is the boiler is oversized. The somewhat longer answer is that the pressuretrol is working as intended, the system reaches the pressure set on the pressuretrol and it turns the burner off. The radiators consume the steam that is already in the system and the pressure drops then the pressurtrol closes and fires the boiler again. The boiler is bigger than the system it is connected to so it is producing more steam than the system can consume.

    So that's reason.. I'm burning my life savings away..on oil..ugh..I think it's time to let it go.. You guys have any preference on brand..Everyone says mclain but I believe they're the most expensive..

    Thanks so much guys..you guys are a blessing to the old guys on here.. I'm sure to the younger ones too..lol

    ok, so, it IS cycling on pressure, not desirable, but not terrible either, 95% of steamers on here are oversized, and cycle on pressure,

    it is safe to say a modern, right sized boiler will be more efficient than yours,
    a lot, no, but more efficient, yes.
    and as far as McClain being expensive, ya get what you pay for,
    but don't buy a boiler name, buy an installer contractor, preferably from this site,
    https://heatinghelp.com/find-a-contractor/

    I just wrote this in another thread, but applies here now also,
    if you're entertaining quotes/proposals,

    make sure the contractor(s) measure all your radiators.
    this is the only way to be sure you're getting the appropriately sized steam boiler,
    Do not accept a boiler proposal sized to your existing boiler unless a radiator survey is done and proves the existing is right sized, (it won't be)

    this is a good 1st disqualifier for any contractor,
    ask your current company for a proposal,
    see if they need to survey your radiators,

    then from any proposing company,
    ask them for pictures of their last 2 or 3 steam installs, digitally,
    you will post them here, and get responses to appropriateness of the prior installs as 2nd qualifiers,
