Here's an interesting ad for someone who needs help with their hurricane 6 engine. Never worked with them myself.
"Looking for assistance with getting a Super Hurricane 6 running right. Seems to be carb.. Carter YF.. putting out too rich mixture so runs on only two or three cylinders with occasional four or five. Ideally, someone might be near with a known good carb to subsitute long enough to drive this gem from Troy to Palouse. Willing to pay for expert help, of course. Thanks, Bob in Palouse 509 878 1471"
