On a carb. car w/SB what do I need to use equipment wise to check mixture? Can it be done at the end of the pipes or do you have to install sensors in each pipe up frt--if so what types and what to read them with? Cost of equipment? Thanks for any advice---
You need a wide band AFR meter to do it the right way.
Cost is between 250 and 500 bucks.
If you can afford it, an Innovate LM-2 or equivalent product will give you much more infos than a simple AFR Meter, and this kind of equipment will also record the results, so you can analyse and compare them with a home computer...
