(Courtesy Marvin Stockman) The Mitsubishi 2.6's carburetor choke pulloff
tends to break; the only fix is a $700 replacement. I have made a twisted
loop (like a hangmans noose) of soft metal wire and place the noose section
around the stud that holds the air cleaner duct. I let the twisted straight
section hang down into the throat of the carburetor. I try to get the wire
as close to the wall of the carburetor as I can. This has the effect of
preventing the choke plate from closing completely, and eliminates any cold
running problem. It is important to use thin wire ( I used soft aluminum
wire) in order to keep the opening small, otherwise the initial idle is
very high. Another solution would be to drill a small hole in the choke
plate. During very cold weather, I pump the accelerator 4 to 5 times and
the car starts right up.
