So I started at the corner store and BANG

[spldart]

I went to start the motor and one revolution and I got a loud metallic bang/thud
sound from inside the motor case. For a moment I thought @$&@#! A valve
and the piston have just french kissed... But when I looked down the tach is reading
1450 rpm... The motor is idling...
I continued a mile down the road to get to the closest relatives house and went
to check things out. I can't find anything wrong.
So I start it back up and headed home. Made it fine. No knocking or pinging sounds.

I am REAL worried even though it got me home.
