boggs on exceleration

[wheelee]

I have 1975 75hp Johnson Stinger, It starts and idles perfectly. But when I excelerate it boggs and dies. Dirty carbs?

Hi, Sculpin.<br /><br />Carbs could be your problem. We need more info to give you much help.<br /><br />"Boggs" is vague. Can you describe what happens a little more in detail?<br /><br />"Starts and idles perfectly" is a too-common comment about engines that are not running on all cylinders. With no load most engines sound fine on less than all. Have you verified that all three are making power? <br /><br />What have you done to try to isolate the problem? Have you tried pumping the primer bulb when she tries to die? How about squirting some fuel mix into each carb?<br /><br />Do a search for power loss and/or bogging and follow the preliminary simple tests.<br /><br />Let us know what you find.<br /><br />Good luck.

Sculpin, had the same problem with my motor and it turned out to be the male fitting on the motor that you plug your tanks into had gone bad. Last thing I figured, but thats what it was. Would idle fine but as soon as I put it in gear and hit the throttle it would bog down. Hope this helps!<br /> <br /> Taz
