Poor Fuel Economy, Even After New Emulsion Tubes

[TDrummer]

I did not change the choke plungers.. And to be honest, they didn't look too good

 

choke plungers, needle valves, etc.

My 92 gets 50 MPG (US)

Has FP tubes, needles, springs and stock mains

I replaced everything on the carbs that could have been worn or rotted including the air box boot and head manifold, so, pretty much everything

 

I think you have more worn parts in there to replace...
