moedip - I could not find a clear gas filter that would be up to spec with the fuel pressure. I checked several stores - one flatly said they're not aware of any clear ones that are up to spec. Which one did you put in yours?

Andy - I checked that vacuum line - it's connected. Bought some carb cleaner to check for other vac leaks and try out your theory of a bad intake gasket.

On a speperate note and off - topic, I can't find any of the approved oils (basivcally avaiation hydraulic fluids) for lubricating the throttle linkage. Has anyone substituted any of these, or know where to get them in the states (or where to order some on the web)?
