The EFI myth

If your engine has cast iron exhaust manifolds and a functioning heat riser valve, setting up the choke system is a matter of understanding how it works. [Assuming the intake manifold exhaust passage isn't plugged with carbon.] The choke pull-off must be adjusted properly [there are specs for this]. The high idle cam must be free. High idle cam screw for cold start RPM. The choke linkage must be clean and oiled to prevent corrosion. Use ATF or thin oil. It may take a few tries before you get it just right.
