I put a new carb on my fj60, and have a few questions for you folks.

1. how do I know if the air/fuel ratio is right? I know where the screw is to adjust it, but don't know if it is set right or not.

2. what should I set the idle to? I have it at about 950 rmps right now.

3. there is no question 3, I just have issues

Thanks folks!

U got ?'s, I got answers:
1. It will show highest RPM or vacuum.
2. Whatever you are comfortable with, or there may be a requirement to set it to the VECI specified speed in your emission jurisdiction.
3. Every generation has it's disease.

?

Treat me like I am stupid (cuz I am when it comes to stuff like this). What will show highest rpm or vacume? Am I supposed to use a guage of some sort to do this (that would make sence)? and if so, what is it called, so I can get my hands on one?

Sorry for stupid questions.

Sorry for stupid questions.
When the fuel mixture is set (the screw) correctly a vacuum guage off the intake manifold will so the highest vacuum. Do a search on setting fuel mixture. Go to a autoparts store and buy a vacuum guage for like $20. I like the mityvac guage.You got a manual? Adjust the mixture screw only really effects the idle mixture. The manual say to set to 650 rpm at idle.

Thanks Kevin!

i bought a manual, but it turns out it has just about everything I need to know except anything under the hood. DOH! I get the engine FSM this next week. (too much money for all these dang books)

I will get the guage and plug away.

thanks again

After you buy the engine manual, go and buy the emissions manual.

Sorry to be the bearer of bad news, but you want the emission manual.
