Engine gremlin?
Bill - explain that one a little bit. Are you suggesting to put some fuel line as a gasket/sleeve on the stem itself to help seal where it screws into the carb? If I understand that right, you maybe onto something. My engine took a pretty hard knock a couple of weeks ago on a dumb thumb error (well the whole plane was nearly demolished) and since then the whole stem assmbly seams a little loose ....
I have replaced all my fuel lines, replaced my glow plug and tightened everything down. I am going to give it a try this morning. Will let you know how it goes.
Thanks ... Bo
