I've had this for probably 15 years. It ran great till 4-5 years ago, mainly riding the grandkids around our fields, till it wouldn't start. It sat for a couple of years till I bought a new battery, but couldn't get it to even hit, so rebuilt the carb, put on a new fuel pump, but no go, so it's sat. Several days ago, charged battery, cranked over and it started??? OK, idles good, but won't rev up, so emptied gas tank, flushed out and filled w/good 93 octane, pulled pump line from carb and have good full line of fuel cranking over. New spark plug, good spark, old one black BAD! Oil change, adjusted valves, no difference. Pulled carb and took apart and cleaned, didn't find any clogs or crusted up inside. Now I've had the carb back off probably 6 times checking, double checking anything I can think of. No gas blowing back in air box. It idles good, can increase throttle up some then starts popping and dropping rpms off and if I don't let off the throttle, it'll die. I've read for 3 days now MECHs and RANDY walking several thru tracing the same problem, tried MOST of the direction given. ???
