One more question Mike,

What did you consider 'low rpm'?

I started up the engine tonight, just to be sure it really worked last Tuesday. Started just fine but there was a
kind of surging of the engine at the lowest RPM. If I increased RPM it started to smooth out. Also increasing the mixture
helped a little, but not a lot.

My question is: is this surging at low RPM indicative of something specific (too lean/rich mixture, injectors not
putting out too little/much).  Something like that?  I am just trying to get a feel for any general rule when running in that
manner.  And if there is no consistency, that's good to know as well.

Thanks,
