Yamaha ox66 issues

[striper56]

First let me thank every one for all the great info and help trying to fix figure out my issue. I learned a lot about the fuel system. It ended up being the little filter on the high pressure pump. After reading about the HP pump I tested for the correct voltage 9v at idle which was good and testing the pressure which was good 35. I found the issue. The little filter on the HP pump was clogged. I washed it off with carb cleaner reinstalled the filter put the VST back together and she ran perfectly. Good for another 1700 hours. Thanks again!
