Evinrude 40 help

[2mate]

Hi there.
On my 1976 40hp pull start evinrude i cannot get it to start. It has had points re gapped, new coils and is sparking well. There is fuel getting in but when it fires fuel pours out of the carb. It has had a new carb kit but i am unsure of the float settings.
Could that be the starting issue?
Cheers

It looks as if the float is not shutting the fuel flow off properly. The float should be parallel with the carb body when the carb is upside-down.

The float and needle/seat in the carb controls the fuel flow, recheck and see if you have a small piece of something not letting the needle close off fuel to the carb.

Checked again today float looks fine its level with the bowl. It fires then wont fire or run again.

Re: Evinrude 40 help

Is it a new float? I usually bend the float arm up ever so slightly (with the carb upside down) so that it closes a little sooner and does not overfill the bowl. With the carb reassembled and upside down, no air should get through if you blow into the gas inlet.

Re: Evinrude 40 help

The float is new yes. Should i bend it so it is slightly higher than level?

Yes, when it is upside down. That actually makes it shut off the needle when the float bowl is not quite so full that it overflows. Make sure the needle is closing properly by the test mentioned above.
