1700 rpm max

[obxairman]

ok last week we ran it out of fuel . Changed the filters and got it running. For some reason it wont rev over 1700 in gear or out. It sounds smooth and not smoking
the linkage is going to full throttle Any ideas

Check the fuel shut off sol. to make sure it isn't broken and holding the sd lever 1/2 way open/closed, maybe fuel pressure, check it, should be upwards of 20 at idle and 30 -35 at high idle.
