Where could I take my regulator to get checked out. When the gas is turned on, the need pegs over into the red an is adjusted somehow through the cutting torch.

Another odd thing i noticed is cranking down on the black knob never reaches the end.

Also, what adapter do I need for these smaller bottles?

I'll leave those questions for someone closer to you to answer.

I see crud in the valve opening. Some of that may have jammed the regulator valve open.

If there is really that much pressure within the regulator and you are making flow adjustments with the torch valve - stop!

Close the cylinder valve. Acetylene is unstable at that pressure and may spontaneously and violently decompose within the regulator and hose, even in the absence of oxygen. The contents of the cylinder may follow.

It may be a missing spring too but I would err on the side of caution.

For the money it costs to replace those, the safety element of working with Oxy/Acetylene is worth the price. Especially as it is acting up, throw it in the bin and buy a new replacement.

SORRY, I mixed different questions together…..bottles are new to me and never used with this regulator.

YES……I AM ASKING FIRST BEFORE I EVER USE AGAIN. ABSOLUTELY.

I took her to my LWS and they said craftsman regulators were very good and they do not make them like they use to. This is a Harris regulator that stopped production in the 1990s. Luckily for me, they have a guy who rebuilds these beauties in his sleep and it will take about 10 days and about $100. A similar Harris single stage acetylene regulator is more than that and I don’t care, this is the real deal. You know, a slice of Americana as we use to know it. Sure , i can buy an AMAZON POS for $40., uh, nope….. what’s a $100 anyway? !!

You are more lucky than I was. I asked Regulator Torch Exchange about servicing my old Linde 2-stage regulators R-80 & R-81. They said no parts are available anymore. Obsolete. They said use them until they start to bleed gas thru then buy new ones.

Fortunately they are still OK. I just thought it would be good to have them serviced since it's been 20+ years now. I would have gladly paid the $125 each for service.
