I've got a 1979 Evinrude 70 Hp motor. It generally runs very well. It always starts cold with no issues, and if it's been running and it's nice and hot it also starts no problem. If it has been running for a while, and then you let it cool down so it's "warm" (for example drive out to your fishing spot, and stop and anchor for an hour or 2) it won't start at all. No combination of choke and throttle seem to make a difference. All you can do is wait several more hours and try and cold start it, and then it will start and run like nothing was wrong. I have also had difficulty replicating this in my yard; it only seems to be a problem when it's gotten nice and hot under load, and then will leave me stranded on the water lol. I noticed that while it is running it leaks fuel out of the intake side of the carbs. I rebuilt the carbs and put a carb-kit in but they still leak fuel. It only leaks out while the engine is running (or cranking), and it keeps good pressure on the fuel line (primer bulb) while not running so I don't think the issue is with the float bowls. Did I not clean the carbs well enough when I took them apart? Any idea if this is what is causing my starting issues? Any ideas on either would be appreciated.
