Propane torch adjustment

>> Went today and got a bottle of oxygen, 50' of T hose, flash arrestors,
>> and a couple of Victor propane tips.
>>
>> Got it home and put it together. Tested with soapy water. Everything
>> looks good.
>>
>> First thing I noticed is when you spark the gas, there is no black smoke
>> to indicate the right amount coming out. The color of the gas is very
>> different, too. Adjusted it to about where I thought it should be.
>> Adjusted the oxygen so that the points of the blue flames are the same
>> with the O2 valve open and when the handle is depressed. The shape of
>> the blue flames is different from that of acetylene, rather like a loop
>> than a cone.
>>
>> Am I close? Any sites you can direct me to with pictures that will help
>> me get the mix right.
>>
>> I'm using 3-6# on propane, and 20-25# on oxygen with a size 0 cutting
>> tip, according to the chart given me.
>>
>> Got it on about four and twenty, actually.
>>
>> I was told by the counter man that propane takes longer to heat up,
>> other than that, it's about the same.
>>
>> Any pointers would be appreciated.
>>
>> I've used acetylene all my life, but didn't want to fork out $250 more
>> for another bottle when I have about eight propane bottles. The charge
>> was the same for any size bottle, so I got the big one, K, IIRC. Will
>> watch for a larger propane bottle now.
>>
>> Got some 7018AC 3/32 and 1/8 and am ready to buzz up some stuff for a
>> neighbor. Looks like I'm welding again after a long pause. Still got my
>> MIG, a Lincoln 175SP+. It's time to make some "stuff". And get a DC
>> machine, IdealArc 250, I'm thinking.
>>
>> TIA
