Listeroid Engines / Re: slow running on start, then slowing down again

It doesn't sound like it's knocking or heavily loaded.
Could it be starving for fuel or air? Check the cleaner to make sure its not clogged with dust and debris.
A more complicated possibility would be a binding governor linkage.
When it slows down, can you physically see the fuel pump rack rod moving to a slower position?
If the rack is not closing, but the engine is slowing, then I suggest air or fuel starvation.
However, one would think that the rack would open further to try an speed up the engine.
( I'm scratching my head on this one )
