If it is a Weber carb there should be a vacuum hose from the driver side bottom of the carb to the vacuum connection on the distributor.

Okay Its a Solex/mikuni. fits all the photos in the factory shop manual. problem is, all the vac ports for the egr stuff are dead/plugged- I can't draw anything out of them with a vac pump. the main intake vacuum port to the distributor is okay, but all the points that the manual says to connect for the air cleaner valve, the egr solenoid etc are plugged. there's three of them total. a tune up helped a bunch, the vac advance is shot. the starting thing is puzzling, feels like the engine just gets mechanically bound up- spins fast, then stops dead, let off the key, try again, spins fast and starts right up. I wonder if there is something rattling around on top of the piston. I'm gonna pull the head to kill the jet valves anyway.
