Hello Everyone A bit stuck here. Tilley 246B 1973 Brand New Old Stock The lamp is pulsing badly Changed the Leather and pip. Still doing it! Air is coming out the gap between the pump piston and its guide. (did the soapy water test) Occasionally the body of the piston fills with kerosene. As previously stated pip has be changed. Thanks for reading Antwhiteman.
Hi @AntWhiteMan thats a nuisance :/ sometimes they just won’t seat with the moulded seal arrangement and some of the square ones seem too hard? you could try carefully stretching the spring but easy to ‘overstretch’ it so be careful lots of folks convert these to the older brass cup holders with a spigot and a slightly different spring which are available on the bay also… i have had good results with using the moulded seals from an ebay seller called arty_pharty so can recommend him for the x246b not sure if any of that is helpful or not but i have been there just a few times! the pulsing is probably low pressure caused by this unreliable nrv cheers pb
Make sure the mating surfaces are clean and not damaged. Pulsing How long did you run it? It can take 20 - 30 min to settle in on the first lightup. Did you give it the 80 pumps on a full tank of fuel?
It certainly should not. The advice already given above is good advice. I wonder how hard the pip is? I note you indicated the pip has been changed but get a pair of pointy nosed pliers and squeeze the rubber pip and it should compress perhaps a 1/3 to a half. If not it is too hard. When testing the pump put the end of it into a cup of water and it should build up pressure when you pump and then you hear the pump squish. Are you feeling the resistance as you pump or is it too easy. You should find some solid resistance as you pump.
A poor seal on the pip is the usual cause, but a split in the pump cylinder or a fault at its foot will both give similar symptoms. Does the pump rise up the cylinder? If not, a split cylinder is a little more likely as a faulty seal or problem at the foot of the cylinder usually means the pump travels up.
