RE: Showtime 50 anyone?
From the downloaded manual, pictures show a hole in the center of the firewall for the stopper and fuel line. It did not appear in the pictures you posted, that what lead me to that conclusion.
And also the Magnum Engine requires that the firewall be at least 5/16" thick (which I suppose is ok for the ST).
Can wait to start building it. I hope to finish it before the snow comes.[sm=50_50.gif]
