electric fuel pump will not have any effect on a kill lever issue. nor will it solve air leakage. it will help in bleeding the engine
, once you fix the kill lever issue.... i have and use my electric fuel pump with mine..
boys will be boys. listen to the lady for a change, will ye????
check your cut off lever issue then work
thru all the fittings and all the hoses. i think you will find that, like mine, the cut off lever is a fail issue.
if cut off lever is the issue, you can try and try and try and try and try and try and try before you give up and call a mechanic
, who will find it inside of 20 mins and you will feel sooooo ashamed you didnt listen to the woman in first place.
