Hello to all

I just bought a 125 ELPTO 1999 model. It wont start pumping water unless I rev up the engine a little bit. Once it starts pumping it does fine, even on idle.
But it will not start pumping till I up the rpms a little bit.
This by the way is by using a water hose and motor flush muffs.

it has a new impeller and thermostat.

any ideas will be greatly appreciated.thanks
