[V8] 10 valve issues

[Jason Wilkerson]

Just a note, Not from experience, but I would think that the check valve would make it crank extremly long, but once it starts it should run just fine.  Yours sounds like it runs bad for awhile until it warms fully up.  I don't know much about mechanical fuel injection, but I would think that there may be a vaccum valve that opens/closes with temperature of the engine?  This valve may allow more/less fuel or air depending how it is plummed.  I would look around the engine/head/intake manifold for a valve that is plummed into a cooling port.  This valve would have vaccum lines attached to meter this.  This could be way off base, but it is worth a shot right?  I will look into this more and try to get back to you.
