Zuk \"diesels\" when engine shut off and Weber ?s
My 87 Samurai had some valve ping, was idling a little high, and running quite rich. I adjusted the idle and set the timing, which was about 14* BTDC. All of my valve ping and noise is gone, no more black smoke, and it idles good but when I shut it off it "diesels", thats what my dad calls it. When I turn the engine off the engine will die for a second and then try to keep running. I have a Weber carb so what do I need to do to fix this?
Also, there are two screws on the Weber that I adjusted. One is a larger flat screw that is on the passenger side, it seems to affect the idle speed, so is this the idle speed screw? The other is on the back of the carb under the throttle linkage and has a spring around it, is this the rich/lean screw???
Which one of these do I turn to fix my "dieseling" problem???
