| Post subject: | 83 Slant 1bl carb problems |
I have been driving an 83 D150 slant since Feb 2014. Just recently idle speed dropped and began getting sluggish and stalling when warm. Believe carb is holley 1945 1bl. Fuel/air screw missing and cant figure out if that is the only prob. When stalls, seems like its choking itself out. Also has a lot of run-on (dieseling effect) not sure what else to do besides rebuild. Don't know settings for carb. |

Does it have the lean burn stuff still on it? |

Are you sure it isn't just hidden behind the factory concealment plug?Quote: Also has a lot of run-on (dieseling effect) not sure what else to do besides rebuild. Don't know settings for carb.
Dieseling is usually a timing problem. I second the question "Does it have the lean burn stuff still on it?" A failed lean burn system can cause exactly the symptoms you describe. |

Positive. The idle mixture screw and cap are not present. Not sure what size. been driving it since Feb and had occasional run-on but now more so. Distributer is tight (hadn't been touched) When truck runs for about 10 minutes it sputters out and is hard to start. must sit b4 starting again |
