I have a 2000 Rancher Es that was having carb issues so I bought a new one.I did this before and it fired right up in the past.This time after installing the new carb it would not crank.It turns over and the rancher is in neutral,but now I get no spark.4 wheeler was cranking before just running ragged.Now it will not even start.I have not replaced spark plug yet,but figured no way it could bad just changing carb right.Any help would be great.
