Thank goodness I found this forum. I'm not very internet savy. I started having problems with engine surging, pulled hose off in front of tank and found snot like substance in hose, drained all fuel in tank, etc., primed but will not start with new fuel. Someone told me that I need to vent the injectors, but JD service manuel does not illustrate corrent location. Any help much apprectated. Thank you in advance Raymand50.
