I am running a 1979 lj80 & having carb probs.
to start with it has poor fuel economy & it will idle fine 1 day & the next it will  barely idle & if I set the idle up - the next time I start it it will be idleing way too high. The exhaust is very rich. Help
Does that LJ80 have a single sidedraft carb? No matter, I'd suggest giving Rick at Hawk Strictly Suzuki a call |removethispart|@ 888-SAMURAI. Last I knew, he had some rebuild kit and, I think, rebuilt carbs for that engine.
Hope that helps.
If that doesn't work, I think you should sell me the LJ80!
