The cold start valve he is referring to is not on the pump. It is on the intake ram.
They leak by when not energized and cause a rich condition.
Some just need cleaning. Some can be re-stoned to seal,
or just replaced.
There are other cold start devices on the pump, but I would check the valve first.
Also, the pumps on the 250-113's hava there own oil res.
and dip stick. [ way down the back, "T" handle]
Be sure there is oil in the pump. Very few know about this as the later FI pumps were lubricated from the engine crankcase and therefore did not have to be serviced.

Let me know how you make out and we can go from there.
