Re: [OMC-Boats] 1969 coil?

Also, even after I had done all the filters and steam cleaned my fuel tank, I still managed to keep finding fine rusty looking stuff in my fuel for several times out in my first season. In my case, it resulted in the carb float valve sticking and not shutting off fuel. This would result in flooding and not be able to re-start the engine.

I can't stress enough that you get that new copper fuel line with the kink looked at, ASAP. You can route the line in such away that engine heat shouldn't be a problem. Or you can wrap insulation around the line, after you iron out the kink.

Subject: Re: [OMC-Boats] 1969 coil?

ill just toss this one out - i had a similar thing going on way back when and had a mechanic tell me it was the fuel vaporizing in the line
between the pump and the carb. he said the flawed design of having
the copper fuel line pass to close to the hot engine might be getting
the fuel so hot it was vaporizing a bit. i think i replaced the
fuel pump or something back then and it was fixed. can't remember,
been too many things since.....
