From idle to about half throttle the LT80 runs good, at full throttle it falls on its face and will stall if you don't let off. If you ease it up to full it will make it but not a snap from half to full. Carb and air box are stock, just under 120 pounds on the cyclinder, new plug, stock pipe. Is it too lean? Recently installed a new throttle cable. Should I move the clip down one on the needle to richen it up? Help.

 

i kinda have the same problem and just kinda thought it/well was told that it was norm. if i hold the lt at full throttle it eventually runs the carb dry. i was told this is from the pitcock and there was no cure. but if what your saying is the 80 runs fine until you go over 1/2 throttle i think i'd look at fuel filter? clogged petcock valve? plugged jet? correct me if i'm wrong but the main jet is for wide open throttle. dont mess with the needle and clip unless the plug is white/lean or black and gas soaked/rich. oh yah if you need further assistance make a post like this in the kid quad fourm. LT80/jack really knows his stuff. hope this helps. pease out.
