OK. had the burner off the tank - nice clean olive at the joint and the thread is in good condition too. The nut and tube are a bit redder than the rest. Is that the copper mix of the alloy? Anyway, the strainer was wedged right down inside the tube - rammed in. I got it out with a piece of stainless wire with a slight hook in th eend (formed by bending to break, rather than winding it round to break it). Hauled it out and the tank end was clean as a whistle. The burner end was kinked to hell and black as the ace of spaces. Gave it a wash out in some panel wipe, dried it by blowing on it hard a few times and left it to dry. Then reinserted it, gently (you'll feel no pain from me!)Nipped th enut back up and fired the old 111. It is still running like a jet engine 10 minutes later - clean blue flame, just like it should be. Good job too, I need it tomorrow - a fishing trip with a friend. Now, the 8R was fired up at the same time, to compare flames....by gum, the 111 is a LOT more powerful. The 8R is going Ok and the burner top is glowing bright red, but there is a little wind, even though they are in a sheltered spot, the blue flame of the 8R is getting blown around and every now and then has yellow tips, not the jet blue flame of the 111. Is it running Ok or is there something I should check with that one too. I really appreciate the help everyone has given me. If Forres wasn't so far I would bring you a fish Henry.
Did you change the filler cap gasket? Take your camera tomorrow and let's see some pics of the 111 in action.
Henry, I know the filler cap seals are good. I replaced them when I got a new pump end (the thread of the tapered shaft was stripped and leaving the nut to come off the end when the pump was pulled to stroke it. So new pump innards, new seal for the lid too. 8R I think is going Ok, but alongside the 111 it looks a bit puny! The top of the burner was glowing a nice cherry red and the main section of the flame was blue, it was just when the wind blew the tips of the flames went yellow - not on the 111 going beside it. The 111 was burning with 8 clearly defined jets of flame and sounding like an English Electric Lightning on reheat!
Well, it cooked the chillie con carne happily, but the flame died again. This time I caught it and there is definitely a pressure drop occuring, because ONE stroke of th epump had it roaring again...gave it 10 good, long strokes and left it going. It was happy after that. Is it usual to have ot give the tank a bit of a pump occassionally, or is t meant to be pressurised just from the heat of the flame once it is going? I don't mind having to pump it....just wondered. Oh, and I forgot to get the pictures. Sorry. I took the camera, but forgot it and left it in the car. So no pics of th efish either - nothing special, only stocked rainbows, but overwintered ones, so feeding fo rthemselves properly and with full fins, no nibbled tails in our 35 acre lake.
Was there enough fuel in the tank? Was it clean fuel? I alway fill my stove with a filter funnel. Not sure one pump would have made that much difference. Perhaps next time give the control knob a turn back to raise the cleaning needle. As you found crud on the filter gauze there maybe some in the tubes. The good thing about that system is when you raise the needle the crud is pushed out. And perhaps next time you'll use your camera
