[Spridgets] HELP Diagnosing a Clutch Problem

[Kevin Valentine]

Hey All,

The clutch is in a 1500 Midget.  We recently swapped engines.  All  
was fine immediately after the swap but the following symptoms have  
begun to surface;

When the engine is off and the clutch is depressed, it feels like a  
normal clutch.  (Easy to push in and release).

When the engine is running the clutch is much more difficult to  
depress and the pressure pushing back on the pedal (pedal resistance)  
is more than when the engine is not running.

There is no noise or vibration associated with this problem.  It's  
just much harder to push in the clutch pedal with the engine running  
than it is with the engine not running.

Any Ideas?
