Goodday.

Our engine keeps flooding whit fuel, whe dont know how this is still happens? New oil sensor and switch everything has been changed, New fuel pump. It started today. It did run today, nut had a to high oil pressure, so whe removed some oil from the engine. And the oil dipstick says its on the oil OK range. And now itnwont run an flood whit fuel again. To little oil ?

Is this a mechanical fuel pump or electric

 

[pascalmekkelholt]

Its a electric fuel pump this year whe did out a new one on of beginning of the season

 

[Bt Doctur]

with a carb the fuel pump pressure cannot be higher than 6 psi.
higher than this will flood a carb

 

[pascalmekkelholt]

Whe have a aftermarket low fuel pump installeren this year.

understand but fuel pressure still must be checked.remove line at carb get an adapter from 3/8ths inverted flare to 1/4 inch pipe thread If its under 6 psi, then suspect a high float setting or a leaking needle and seat in the carb
