1966 40hp rude dies out on water fuel dripping from carb

[skinny1965]

I have had this happen twice to me .
the first time had been out for few hours (4 or 5)fishing and moving the waves came up a bit so headed in boat was pounding a bit in waves then it died. pull off hood and carb is drooling fuel. I taped carb thinking stuck float with no luck . I got towed in.

I took the carb off blew it all out (was clean) couldn't see issue put it back together and all seemed ok

Second time Last Sat out fishing water was calm to start . got out a fair bit and the wind picked up some headed back in pounding some waves then it quit and card drooling . This time I got it to run not well at all but enough to limp in .

When i got home pulled carb off and down again . Once more I see nothing to cause the needle to stick . float is set level and needle seems to be smooth in bore

the carb was rebuilt last fall with all new parts but the float

I did sink the float in fuel for about 3 hr and it floated after so I'm not thinking it is sinking

What a coincidence, I currently have the carb from my '66 Johnny tore down for the same reason. What are the odds........

Anywho, what I have discovered is that the stop arm on the float was catching the washer under the needle seat. Not all the time, but it only takes once to flood out. Have not had a chance to do any more to it, hopefully I can trim the washer or find one slightly smaller in diameter.

Maybe this'll be the cure for both of us. Good luck.

When you turn carb upside down how far does the float fall...it should be around 3/4 of an inch.

in looking at mine I didn't see that but maybe I will pull the carb off and check again . mine is kind of a pain to remove seems the starter and generator is in the way of mounting nuts

Yep, same as mine. I can have the carb off in 15min. or less
I've had way too much practice at it......
