Hello all!
Earlier this year I acquired a 1986 70HP oil injected Yamaha. I have had it on the water twice and have run it on muffs a couple of times with no issues other than a small leak from the carbs. Thursday I pulled it out to hook it up to the muffs one more time before hunting season. Fires right up, runs for about 5 seconds and dies. Won't start at all. Pull air cover off, and there's a puddle of fuel in the bottom. I assume sticking float. Already had a rebuild kit just in case. I rebuild carb, clean everything up, new fuel, still no go. I've had carb off 3 different times making sure I didn't miss anything. I'm feeling pretty confident it's not a carb issue. I also replaced the plugs with no luck. I did confirm I have good spark.
If a spray a little fuel mix directly in the air intake, it starts but only runs long enough to burn off the spray, which leads me back to carb, but I don't know what else I could do with it. I've checked all the holes, ports, etc, and they're clean.
I'm going to pick up a gauge to test compression, but I don't think that's my issue.
You guys have any other ideas for me? Am I missing anything?
I went through the previous topics for as long as I could stand, so I hope I didn't miss this previously.
Thanks for any help you guys can offer!
