\015\012An adjustable fuel regulator is a little under $100.\015\012

\015\012As a test you may spray SMALL AMOUNT of starting fluid into the intake and see is the engine is ABLE TO RAN. \015\012
\015\012DO NOT OVER DO IT. This is just a test.\015\012====\015\012
\015\012Get a timing light attach to cyclinder #1 and see can does it pluse as you cranking it.\015\012
\015\012Don't bother to look for the timing mark. \015\012
