final assembly of the main bodies.
flip the middle,main body upside down.there are raised ridges like shown on 2 of the bolt holes. this ensures alignment of the parts,also ensures the gasket is on correctly,as it fits only one way.i like to grease these gaskets.
before the bottom plate is installed,i want to point out the 2 vacuum ports.the small orifice the staples are pointing to. both left and right front ports are "ported" vacuum fitting,little to no vacuum at idle,with vacuum coming in after throttle is opened.it's accomplished simply by putting the ports above the throttle blades.as the blades swing up past those ports,the engines vacuum is exposed.remember,vacuum is under the throttle blades.
notice the right,passenger side orifice is positioned a little higher from the throttle blade than the left,drivers side. that means the right side gets a vacuum signal a bit later than the drivers side.that would make the passenger side port the EGR port,and drivers side the ported DISTRIBUTOR port. the distributor gets vacuum before the egr valve.
position the bottom plate over the main body.drop the 6 screws into place,and snug them,progressively.the allen screws are not stock,i got them since this carb had mis-matched screws when i got it.
flip the carb over. place the small steel ball into shown position. the brass check valve for the accelerator pump is also installed to the right.point down.
the upper gasket also has the locating bosses,indicated by the orange dowels.put the gasket into position.
install the float and needle.the nailhead of the floatpin must be on the shown side,or it will slide out in use.
lower the airhorn into place. you will have the accelerator pump plunger,secondary plunger,float,emulsion tubes....all must be in position,before the top will lower into place. DO NOT FORCE DOWN!
one screw out of the 10 that hold the top on is longer than the rest,it's hole is the one shown by the orange dowel,lower left. all screws will be progressivly snugged down.
after i get the choke pull-off pot for this carb,and do a few things like plug the vent fitting,we'll put all the linkages in place,and do the bench adjustments on the choke.and it'll be ready for service.
