Hey all having a problem with my car when I turn the ignition off it runs for a while then stops. Now I have used a gunson colour tune and it's spot on in mixture and timing is 5 deg at idle and still runs on what causes this any help would be appreciated thanks |

Maybe a carbon buildup which will create a hotspot on the piston or underside of a valve. What plugs are you running? Try dropping a cooler plug in to see if stops the run on? Cheers Shane |

Yep, colder plugs have helped me in the past. Also I have used Redex in the fuel tank and gunned through the carby at times. Then a quick flog out the road. |

Too high an idle & too high compression will help "run-on" Back off your idle screw a tad & drop your initial ign timing a tad. Maybe 2 or 3 degrees & that should help... If it does then sneak up your ign a bit by bit but keep dropping idle to suit until you find a happy medium between idle revs & throttle respinse without the run-on when u turn it off Have u got a compression tester & a taco? |
