I couldn't find the Coleman catalog no.22 but did find the old coleman papers and in them the parts list and suggestions for the 2E and 9E stoves. In them a tantalizing hint and I quote "Cause -Bent or broken Cleaning Needle. Remedy - remove generator regulating stem and install a new Needle and holder, then replace in generator" I wonder if this means the little nipple end on the regulating stem that I found tonight (which unscrews), is in reality the "Needle holder" and can be bought to renew my generator?????? Wow, that would be wonderful because that's all that's wrong with my generator, a broken needle. I might even be able to drill out my existing holder and replace the needle with a bit of guitar string (steel) like the English do to make prickers for their swedish stoves. I'd bet common solder could be used to hold it in place because it wouldn't get too hot what with fuel passing by it all the time anyway. Stan.
