It will idle all day long. but at WOT it will stop after around 30 sec. and is real hard to start then. it looks like it stops getting fuel at WOT. Does someone know how to fix this?

Also, make sure you are getting air back into the tank through the vent. I forgot to open the vent once and the plastic tank started to slightly collapse and my 115 didn't want to keep running very well, for obvious reasons. These big girls like their fuel at high speeds. Your vent might be plugged or just not big enough.
