Right...however, there was leaded fuel back in the day making it much easier to read plugs. It's not impossible, but no where as easy as it once was, especially on a well-tuned plug. It takes some miles to leave a pattern.
Plus, you'd tune both fuel and spark by fastest times at the strip, especially mph. This in conjunction with reading plugs and usually a notebook and years of experience depending on atmospheric conditions due to past set ups got you to where you wanted to be. IF it wasn't the strip, it was the dyno looking at the area both below and above the curve and knowing when and where to pull/add timing. Bronco owner's aren't looking to do this. 99% of them couldn't even say how much mech adv or vac advance is being added or what it adds up to.
How many will actually look down to the base of the ceramic on the plug? Know to look for the change at where on the ground strap to tell total vs base? Plus, this leaves the reading wide open to human interpretation...almost as bad as officer discretion. Especially without years of reading plugs. Knowing is great and backs up the wideband and what one has already measured via timing light.
The point is, when I make a recommendation, it's easy for the DIY'r and doesn't require a butt load of reading and education prior to just trying to dial in a carb.
MTX-L is one of the most accurate and cheapest available on the market. It takes out soooooooo much guess work and interpretation. Yes, it is a single, but we aren't tuning a SEFI here with individual injector control per bank along with EGT's, so let's keep it simple. The kit comes with a bung, but you will need a plug if you don't plan to not run it permanently.
The vacuum gauge will be awesome in letting you know where your PV opens up and then you will instantaneously see it on the gauge. When it opens up, it will drop typically two points on the AFR.
By all means, if you take the challenge and mount a MTX-l and start dialing in your 2150, add to my thread your combo with measured timing (base + mechanical+vac and port or full) and what you've measured along the way. It's why I started the thread, for those who love to measure and post results to help the community.
