alrighty guys, first off i'd like to say Hello as i'm a new member on here.  secondly, I've owned my 86 samurai since august of this year and i'm loving it!   
however, I recently rebuilt the carb(weber) and can't for the life of me figure out where i went wrong.  I made sure the jets were put back in the correct spots just to clarify(i'm not a complete idiot lol, although sometimes i suprise even myself!   )     
It is driveable, highway speeds as well, but when i go offroad( even the smoothest dirt trail) it begins to have a fuel issue, as if it is not able to get fuel.  it sputters no matter how much i step on the gas, and then if i let off it dies completely, as if it flooded out.  the float is set at the proper drop as well from what i can figure out... any ideas?

I am no carb expert by any means, but I have heard from the site that the webers are problematic. Was the weber on when you purchased it?

yes it was on it when i purchased the vehicle.  it was leaking fuel out of the accel pump, so i just went ahead and bought a full rebuild kit.

Two diametrically opposed conditions - perhaps you should start by determining which it is.

If there is a fuel supply issue (ie insufficent fuel) it will be noticeable at highway speeds, so I would think that is not the case, so let's look at the reverse - excess fuel or flooding.

Webers are known to be relatively sensitive to fuel pressure - and in a situation where you have marginally high fuel pressure, additional vibration from off road use can unseat the float needle and cause flooding - what sort of fuel pump do you have, is there a fuel pressure regulator and what pressure is it set for.

Try lowering the float by 1~2mm and see how it responds.

Webers get a bad rap from people who don't understand them - they are no more problematic than any other brand - however - they are more "flexible", allowing them to be tailored to different engine requirements, and that flexibility requires a better understanding of what you're doing.

Did you manage to solve the issue with your carb. It sounds to me that you have your float adjusted too high.
If I remember correctly the correct float height is the fuel valve closed fully about 1mm above the horizontal.
And the swing of the float only 2 mm from closed valve position...note this is unique to Sammies.

sadly i haven't bothered with anything on my sammy since i posted.  trying to get school done for the semester so that way i will be at home and can completely take the sammy off the road for a couple weeks during the break.  so i will start messing with it in about 2 weeks.  i will definitely post back on here.  out of curiosity, if the float drop is at 18mm(that is what the paper in the rebuild kit said it should be at and i measured) does that mean i need to go to 16-17 or to 19-20?  i'm sure as soon as i have it out it will make sense to me but in my head i can't see which way to take it.
