Yes, I have the same splitter.
He needs to drop the bowl nut off and clean the nut/jet first, see if that helps. Mine is very bad for getting water in the fuel/carb. He might have to remove the carb and go through it thoroughly.
BINGO!!!!! Boudreaux and ILEngine were right. Cleaned out controls and cleaned nut from bottom of carb ( not very dirty but I think it had some water). put it all back together and it fired right up. THANKS guys. Now to teach my Redneck neighbor about proper maintenance.
