I've got to ask this:  Is there any real difference in the way an OS 
1.40RX runs with the Mintor 1.40 head 'extra' plug in the 'front' or 
'rear' position?  I know that Lance says to run it with the 'extra' 
plug in the 'rear' position, but I theorized that there would be better 
fuel ignition if the 'extra' plug was in the 'front' position, as far 
away from the exhaust as possible.  I've been running mine that way and 
the engine runs fine.
