Foxy Green Foxbody Build

Get yourself an AEM or similar wideband and put one in your car. Hell, I have one in my everyday Buick, love them! You will get to see exactly what is happening. Most likely a lean spot, but you never know until you actually know. I felt my Buick laying-over at full throttle after a few seconds, found the thing was going down to 9.2 A/F. Those dumb fucks send it way rich as a catalytic convertor saver. Would never have known what was happening without the wideband. I was able to tune that out.

I have two gauges. Each collector seems rich at the moment.

I'd guess almost every carb company will err on the side of rich.
More or less depending on what they know about your setup and how good they are.

"Lean is mean"
 
The pump nozzles are 35. I'll call atm Monday and see if they think I could bump them down a few
 
Already blaming the carb. 😆 How about setting timing first. You said that you don’t even have a light. That’s where I would start.
 
The light worked fine.

16 initial. Adjusting timing didn't do fuck all. This is why I don't come to this forum

Patriot is a good guy and we both know that, don't let one post irritate you.

As for timing, I'd listen to what the engine wants but IIRC your cam is about 245 intake and that would generally like more initial.
I will guess that when you get all your tuning set it'll like a bit more than 16.
 
When I was running mechanical advance, I ended up using this machined bushing. The MSD one will not allow you to run enough initial timing. Without going overboard on total timing.

I bought those bushings too but there's an interesting post from years ago by "Tuner".

He says that it's better to bend the weights to achieve the increased initial.
I bought a set of weights, and they are patiently waiting for me to bend them... :)

I'm in the middle of changing the coolant on my truck but I'll look for his post later.
 
For a fucking ford ranger :p you are doing good. Nice lumpy idle ya got there. :thumbup:

Just a little advise take it or leave it. Take your time and it would be best to log all the carb changes especially the base settings that it was on (where you started). Then take your time making adjustments and noting down the change if any. Being a rookie at it you can forget what you already tried and start going in circles. There really isn't that much to adjust so take your time and methodically work through the settings.
