Ok here is my dilema, i have both these smoke generators and feel that the 7226 smokes better and smoother than the 72270, now i have the 7226 installed in my 37883 steam Loco, and the 72270 installed in my 39020 Steam loco, now of course installing them is different for each, one goes thru the top, the other (72270) from the bottom. Well when i first installed the 72270 it barely smoked, i then removed it and straighten the little metal pin so that it made better contact with the metal part of the loco somewhat, and now it smokes great but the smoke barely last around one loop before it appears as though it has ran out, it appears the the 7226 holds more fluid than the 72270, also these smoke generators are a tight fit, and i hate pulling them out and refitting as it is a P.I.A holding the little loco, since i dont want to break anything. One last thing, on the 72270 how much upwards do i have to push it and know it is sitting correctly? Thanks in advance, and if anyone has any tips please feel free to help me out, i am sorry for my dumb question!

I have had similar experiences with smoke generators : I have had ones which smoke for a good time and ones that last for one 30 seconds or so. Upon careful examination of the ones that last for only a short time I have concluded the following. The ones that smoke for a short time have some damage or fault with the central tube. In a normal situation the tube warms throughout most of its length and thus smokes until the oil is near the bottom of the brass outer tube. In the short smokers, the central tube , only the top part warms and hence when the oil is used up to half way down stops. So much for the observations....... The cure..............That I still have to work out............

Hi,

It should last way longer than that! You might try another one, unfortunately is it just mystic powers that makes them work - no joking.

What I do is just stick a syringe needle on top of the smoke oil bottle and count the drops. 72270 normally takes about 8-12 drops.

Have you ever tried to stir the fluid with thin wire ... might help - just place the loco on track, put in oil, turn on the smoke and stir the fluid; there might be an air bubble stuck inside ...

Oh, one last thing: what colour is the bottom of the generator? If it is not red then it is not for digital. I've had a regular one (green) and it just broke leaking fluid.

No problem ... would be happy if it will work!

Drop us a note!

Hi Cem!

I didn't know this.
I have a 7226 in my BR50 (#3315) converted Digital with lokpilot, but it doesn't work good. It lasts few seconds. It has the green bottom. Do you think I would have better results with 72270?
