Any savy wise comments regarding this darned matter? Low fuel boost makes engine run rough and reproduced detonation described before.

You might have a bad mag that is passing ground checks. Jeff -------------------------------1110753348 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable
