Yes, that is the screw and spring that I need. My address is John Turner, 76 Bogel Road, East Haddam, CT. 06423, include your return address in the envelope when you send it to me and I'll drop $5 in the mail to you for your trouble. On the heater rerout, If it were me, I'd skip the intake manifold altogether, get a premeasured fresh piece of heater hose and hook it in to the sources on the heater core and then the block. I think that the only reason it connects to the carburetor in the first place is to actuate the automatic choke via the water temperature. (kind of a low tech approach.) Good Luck and Thanks a ton for sending the screw and spring to me. jt
