34. Locate the nut (11.3) securing the heat shield bracket
(11.4) to the stud (11.5) on the heater return pipe.
Remove the nut and save it-we will need it later.
35. Remove the heat shield bracket (11.4) and the heat
shield (11.6) by pulling it up and off the 4 carburetor
studs and the stud (11.5) on the water pipe. Set it aside.
36. Remove the four studs that secured the carb to the
manifold. Spray the studs with penetrating oil and let
them soak. Double-nut the studs and unscrew them. If
you have a stud puller, use it. Since these studs will be
discarded, you may use vice grips if necessary. If the
studs won’t budge at first, let the penetrating oil have a
chance to soak in for 30 minutes and give it another try.

37. Once the studs are out, scrape the surface (12.1) clean
using a gasket scraper and/or single edge razor blades.
Spraying some brake cleaner on the gasket residue will
soften it, making it easier to scrape off. Although
missing in the picture, keep a rag stuffed into the hole in
the manifold (12.2) to keep debris out. Be careful not to
gouge the surface.
If you took your safety goggles off, put them back on before
to do this step! We must clean out the threaded holes in the
manifold because we will be using Loctite on the bolts that
secure the throttle body, and the penetrating oil residue will
prevent the Loctite from bonding with the metal.

38. Spray brake cleaner into the holes while holding a rag
over the hole and the nozzle of the can to catch the
splash back.
39. Remove the heat riser. The heat riser (13.1) is secured
using one on the manifold nuts (13.2). Remove the
manifold nut using a ½” socket, extension and a ratchet.
40. Remove the heat riser and replace the manifold nut. Use
the torque wrench and tighten the nut to 15 ft-lbs.
This concludes Part 2 of the installation.
