As I said, whether running wide open or idling along, the engine will suddenly stop.. Wait 10-15 seconds it will usually restart and run for a distance.. 

So far, I have drained and cleaned fuel tank, changed fuel filters. fuel lines, fuel pump, breather filter, and lastly the carb!!

I have the parts list and also the repair doc... I have a question about the hose that comes from the fuel pump and goes into the crankcase.. What is inside the crankcase that has to do with this hose. I can't find it anywhere in the parts list or other doc  Hopefullyelully someone can help me with my problems
