Is it chilly in the morning when you start it? If it is I am very jealous since I live in Vegas with 90° lows...
...anyways, I was wondering if your choke is working? All a choke does is enrich the mixture which is essentially what you are doing. |

I'm afraid if I mess with the idle mixture that I'll do more damage than good since I'm clueless at this stuff. |

Ok, It's been a while, but I did get a timing light and adjusted the timing. I still think it's a carb issue. I ordered a new vacuum advance, so I'll replace that and see if it still backfires on high rpms. I doubt that will fix it.
I want to make it a daily driver so I may replace the whole carb altogether. Does anyone know the right carb model and order number, and do they make a new carb for the 351e V6? I'm wondering if I'll need a special adapter to make it work? I looked at Summit, and LMC, but can't really tell. No one ever lists the 351e. Thanks for any info guys, I'm still pretty new at this, but I'm learning. I love this truck and want it on the road. |
