The Ford Barn

Hi All,

I am trying to tune/solve problems with my 8Ba and am hoping I can recieve some guidance,

Problem one is that I have a 94 carb and it is running super rich at idle ( fumigating the shed rich), I turned the mixture screws all the way in and the engine responded very little other than idling a bit rough then eventually died after 30 or 40 secs. I do remember reading that someone had a similar issue but I cannot find the post to see what the actions where to work through. I assume it has to be float level or leaking power valve? As it must be flooding/running off main circuit somehow?

It is a brand new ( reproduction) carb, could anyone offer.

My other issue idle trying to find a good guide to
Tuning the engine in a step by step guide ( not tuned to much before) including,

1. Using the vacuum gauge and the best spot to connect, what different reading mean.

2. Setting the gap on the points, what to set at etc

3. Setting the timing, what to set at? Do I disconnect vacuum advance to set initial or leave it on etc.

Is there a good guide/page someone can suggest that is detailed on the above info or what order to do it in.

I have seen a heap of posts etc but have not found a full guide on what to do and the sequence.

Appreciate any information

Cheers

Corey
