Johnson 115 - No Fuel getting to motor

[johnson1fifteen]

1979 Johnson 115 Motor - I was having problem with motor running hot a couple of weeks ago and I checked: Compression and was running 120, 121, 120 & 110. I removed the heads and found that the heads were scaled up bad and cleaned and reassembled motor. I rechecked the compression and it is on at 130,130,130,129. I tried starting the motor but would not start. I used a spray bottle and started the motor with the spray bottle but would not run on its own fuel pump. I rebuilt the pump, since it appeared to be original and still have the same problem. The primer squeeze bulb stays firm and appears that fuel is not being pumped. I checked the pulse port for the pump with a gauge and was getting pulse. Not sure what pressure I should have. <br /><br />Any ideas?

Did you try to disconnect the primer bulb/fuel line to the engine? Try that- pump the primer bulb<br />and hold the open end of the hose into an empty jar, can to catch the gas. Make sure none of your lines are kinked. If you have a built in fuel tank on your boat- trace all the lines.

After further checking I found that both floats in both Carbs were stuck. Rebuilt the carbs and is now working fine. Thanks for you response Sal G.
