hopefully this is the last post about real problems...... new to me 753 seemed to loose it's prime when shut down, once the system was primed the power seemed fine... the machine is supposed to be for quick jobs that would take 5 min with the skid steer that would take an hour by hand (or more likely get left).... this problem was getting to be a real pain in the ass as it would take longer to get the machine running properly than to do the job. it turned out to be the fuel stand off in the tank. when I pulled the 90 degree fitting out of the tank the standoff and screen fell right off. I put a peice of clear plastic hose back in its place and connected the system back up and hopefully bled it for the last time...... hope this helps someone out
