Engine flush products in the oil will reduce some of the varnish/deposits 
internally, but won't affect deposits on the intake valves...

Perhaps you have heavy deposits on the intake valves... initially, the fuel
is soaked up by the deposits, leaving the mixture lean; once it's run a bit,
the deposits are saturated, and it runs ok...
I think you can have the valves walnut shell blasted in place, or try one of
those heavy duty cleaners...

Before you do this, make sure you go through the troubleshooting procedures
