Unit is RK-21 16hp vanguard / TS2021 5.5@3000 5.5 tip 12v hotwater
Problem #1
Replaced the unloader. K 7.2 worked fine. Now it seems to take a long time to come off of bypass. If I take off the tip, purge the system , put tip back on it works right a way. Otherwise It just wont come out of bypass. This seems to happen when using hot water, which is always. Every thing seems to be set correctly. Also I just resently descaled system. Any suggestions or help.
Problem # 2
When machine pressures up there is a instantanous lag in RPM when the pump loads pressure. Then it goes to full RPM. This never did it before. Resent oil change, new air filter , new plugs.
Is the motor just wearing out? Has about 1500 hrs on machine.
Sometime it makes you go hhhhhhhmmmmmmmm.
Thanks for the help.
