Impossible mixture screws

[ZiRiu]

How you you guys access the mixture screws with all the vacuum lines, accelerator pump, and fuel filter in the way? I was just trying to adjust my carb but there's no way to get a screw driver onto the screws and I even tried using a pick at a weird angle with no luck.

This pic looks similar to the junk I have in front of my carb.

Really loooong screwdriver, or really short one whichever works best, but a standard length one isn't going to work.
They also sell fancy carb adjusting screwdrivers, but I never liked 'em.

Or ditch the carb and go fuel injection

I have a foot long philips but not a flat head. Guess I'm going to harbor freight.

There was a post a while back where someone installed a short piece of rubber hose over the screws and then a piece of dowel, with a slot cut into the end, in the other end of the hose. Said it worked great and it did look good.

I have used fuel line (don't recall the size) over the idle screws. Works well as long as they are not stiff.

Google Carburetor Screwdriver, about $15 and you'll never try using a regular screwdriver again.

Haha wow, it's amazing someone had to come up with that. I'll have to invest in one. Might try the hose trick to get her tuned for now.

Really long flathead screwdriver works for mine.

I couldn't find a carburetor screwdriver at harbor freight so instead I got a 22 inch long screwdriver set for $4.99. I smoothed her out best I could and I'd say it's an improvement. I thought my ignition coil was going to fly off one of these days.

The passenger's side screw was almost all the way in.

Looong or sometimes stubby screwdrivers are your friend. For soft easy turn mix screws doan worry about NASA quality/country of origin."Length is the key"

Ok wow. I just got done doing a pretty rough tuneup (will try again later this week) and the results are like night and day.

This is a video from a week ago when it ran like crap

And this one I took like 15 minutes ago. It's like a whole new Jeep.

If you adjusted the screws differently on each side, you aren't supposed to go there. They are supposed to be adjusted the same, each side. Turn one, then turn the other the same amount. Rinse and repeat. To start out, seat both completely, them turn them out the same distance (2-2.5 turns?) with the engine off. Start the engine and adjust them in in tandem, say in quarter turn steps, until the idle speed drops. Then back off to the previous step. Done.

[ZiRiu]

That's what I did. Both sides were 1/2 a turn from seated so that's probably why it was running so bad.

I just went out to clean out my carburetor after it was running so rich for god knows how long and I noticed the engine will run fine with the idle speed screw not even touching the throttle. Did I not tune it right or could that be a vacuum leak?
