Another Question about my 84 bronco II with the carbed v6. I cant seem to get the idle and mixture correct on my bronco II.I check out the post a few pages back on how to adjust the mixture screws and I am going to try it, im hoping that its a good way to do it (let me know if it isnt).if that doesnt work I think I just need to buy another carb since this one is the original. I thinking im running a bit ritch right now as when I start i puke some black smoke out as well as a bit of burnt oil. The idle I think is set pretty close to where it should be at this point. Im not the greatest mechanic in the world of back yard mechanics so i was woundering the best way to be sure my idle is correct. any help would be awsome, Thank you again, this site rocks!


the post im trying for my carb....

Not familiar with this motor. What does it have for a carb? Don't know if you have 1 screw or 2 but, it don't matter. Here's an easy way to do it and it will even pass emissions if required. Start by turning the screw(s) in completley then back out 2 1/2 turns. Start engine and let it stabilize. Make sure RPM is close to spec. Make sure timing is correct... O.K...now turn screw(s) in 1/8 turn at a time, allowing about 30 sec's for idle to stabilize after each turn. You will reach a point where the idle will drop and even get a little rough. Stop at this point. Now turn the screw(s) back out 1/4 turn and leave them there. If you notice any problem like backfiring on decel after this, turn them out 1 more eighth turn.
