Hello,
I have an '86 FJ60 that failed the CO portion of the emissions test. Limit is 40 and I registered 108 (I don't remember the units).
The truck has had extensive work in the last 3 months fixing oil leaks (oil pan gasket, rear main seal, side cover gasket, oil sending unit) as well as a general tune up that replaced every hose under the hood, new spark plug wires, and numerous other items. I don't think compression is the problem.
I am new to this vehicle and I haven't had a chance to poke around on this particular problem, but I'm guessing the fuel mix from the carb is too rich. Can anyone recommend a manual or web site that will tell me how to adjust the carb to add more air?
I need to know what to look for to determine if this is the problem. I would rather fix this myself than pay a shop $500 to adjust it for me.
Some info about the truck:
2F engine
147K miles
stock carb
running 87 octane
oil changed 2 month ago - I run synthetic
choke works fine, I have to use it to start first time each day
