Ur-q fuel system troubles

[OHOE <OHOE@aol.com>]

Hi, I posted about this a couple of days ago but got no responses so I thought
I'd try again with some new information. My Urq is running very lean. It
doesn't like to start very much when it's cold and really doesn't start very
much when it's hot. Power is also greatly diminished, although at certain
times the power comes back for a little while and then goes away again. What
does this sound like? System or differential pressure regulators? Pump? Check
valve? Distributor? I'd really appreciate any help, and soon, please. I'm
supposed to be taking the car somewhere a good distance away tonight:(!
Private responses would be best as they get here faster than the digest.
Thanks so much (fingers crossed),
Oliver
