Yes, we are speaking of an 82 CSR 305. The hose I´m speaking of is to the left of(or just before) the choke. I did see the other ones that are drains as you mentioned and they do go to the left. This might sound funny but when I blow into the hose as hard as I can the engine turns over and sounds great (very quiet) but as soon as I run out of air she quits! I think I might have to go down to the library and get a repair manual for this one.
