I have a 15 hp jhonson rebuilt carburetor when I choke carb give a couple of pulls it fires . Pull open choke gas runs out of carb. It did the same thing before rebuild of carb . Motor sneezes when it fires or barely runs . I know carb is right any ideas. Thanks
Sneezes and dies shortly after it starts? Spits fuel out the carb?
Both are signs of a lean fuel mix or broken or dirty petal on the reed valves. Might want to pull the carb again and take a close look at them using a small flashlight. Better yet, remove the reed plate completely for a closer inspection to check for broken petals or dirt holding one open. It’s also a good idea to have new gaskets on hand first, just in case.
If the carb is adjusted correctly, leaking crankshaft seals can cause a lean mix by allowing air into the crankcase.
