Re: Q-jet over flow line question..
Okaaay...Now it comes together. Thanks Bondo and Rodbolt...<br /> <br /><br />I didn't have a clear picture of the function being so auto oriented. Now it makes sense...<br /><br />I used the old 1979 carb on a 1983 Kayot I repowered this spring. It came with a diapham line. However I failed to notice that till I had already rebuilt the old '79 carb (used it because it was in very good condition looked new, just had been stored). The original carb was in sad shape. <br /><br />Well, when I got the engine built and set in ... was when I noticed the diaphram port was missing. I used the carb anyway for the memorial weekend and plugged the diaphram line at the carb, and left it connected to the pump. <br /><br />The carb performed flawlessly...till the wife and I went out one last time after a big weekend and family reunion. The engine died and the carb flooded on the manifold. Being a mechanic I noticed the odor and found the problem immediately, but was still thinking that it was a return line. Hence the query...<br /><br />Now that I see it is a fuel pump safety feature...is there an easy way to enable it to function , perhaps a small metal line (wiper washer tube for instance) adapted to flow into the venturi....anchored to a carb screw perhaps. It's a first rate low hour carb...guess it got a little trash under the needle seat. Had a new water separator/filter by the fuel pump and a new carb mesh screen filter (from a new Sierra carb kit). Ran great except for the overflow last trip out....don't like that at all since one of our family might not notice the odor, and there is a square 25 gallon fuel tank sitting adjacent to the motor on this deck boat.<br /><br />Would like to keep the carb...thought it was a gem. But really am puzzled about the overflow...with new filters and all...could be a dangerous situation.
