bike runs as long as start fluid sprayed into intake. no fuel coming thru the petcock in any position. pulled petcock out of tank. air blows thru large orifice, not small one(vacuum hookup?). any ideas on what to do next? a friend thinks petcock may be operated by a vacuum diaphram, thus the vacuum? line. thanks for any help.
