Thanks, all.

Just purchased a 65 250SE sight unseen.  Supposedly perfect original shape,
inside & out.  Saw pictures & it looks mint.

Old person selling it said it just wont start.

Now, aside from the obvious (ignition/spark/fuel supply)  is there anything
else MODEL SPECIFIC that I should look for as being the problem?

Keep in mind, there has never been an engine put in front of me that I have
not gotten running.  I'm just trying to save some time when it gets here, by
one of you saying something like "Oh, yeah, the 65 with the mechanical
injection has a gooodiddy valve that sticks sometimes cutting off fuel" or
something like that.

I really appreciate the assistance.

Mike
