My grandson was given a nice Cub Cadet 122 with a K241 Kohler engine. Was able to get it running fairly easily by cleaning carb and cleaning and setting the points. The problem we are having now is that if you crack the throttle the engine stalls. If we open the throttle slowly the engine takes the gas and runs fine. The carb is clean and is getting plenty of gas from the tank. I've had this problem with other engines in the past and was able to correct the problem by adjusting the carb. No matter how I tweak the high and or low adjustment screws the problem stays the same. I'm thinking could it be a leaky intake valve? The engine starts up easily hot or cold, and the problem exists hot or cold. Usually a valve problem will show up with hard starting at some point. I might add that it looks like a new carb. The previous owner had it set up as a pulling tractor and seemed well maintained. It had sat for about a year though with out being started.
Figured I'd ask you guys cause someone might have a simple answer.
