My little Coleman is still unlit. Assuming that all seals will need to be replaced where will I get them and which Service Kit? Also, I am still waiting for literature and instructions from a certain CPL member - no names but you will know who you are Neil!
Try Mike at old coleman parts,normally the pump leather will respond well to a good soak in clean engine oil,you can use a "o"ring for a cap seal,that may be enough for a trial run,give the tank a good rinse out,does the valve wheel turn freely and does the pricker lever rotate,there are a number of variables with old lanterns it all depends how long ago they were last used,good luck,tony
