The blower and sprayer worked better in the 3&4 outlets but still not getting enough blower pressure.

Have a 7300 JD....an older one with a valve on the end of the blower hose that goes into the outlet......it did not make a difference if the metering valve on the end of the hose was open or closed so maybe the check valve is stuck closed.......got it loose now so will try again tomorrow.

Thanks for the advice
