Cheap (relatively) way to get the car running is to install a 4BBL to 2BBL conversion plate (Holley carries them for about $30), slap on a 2BBL carburetor from a '70's era Ford product and do some rerouting of the fuel line. I ran my '73 W114 with a M110 for several months using that set-up. That will allow you to determine the condition of the engine without having to piss about with the Solex.
