I rebuilt the Holley 2bbl on the 2nd Owner of the private shop I worked at's Dad's '87 Dakota 3.9. Always smoked and ran like s*^t cold since it was new, for 20yrs, nobody ever did a thing about it. When I rebuilt it & was setting it up, I realized the pulloff link was slightly twisted, causing it to drag & bind the "U" hook under tension. Tweaked & set, it will start & run at -10°F, drive away no problem...I bought "Trusty Rusty" a year later off of Him..
