1990 60 ELPTO bogging down at certain point on throttle

[tomjones_100]

I have a 1990 Mercury 60 ELPTO that boggs down at a specific point on the throttle when put into gear. It starts fine and idles ok. Once I put in in gear it will run slow OK until I increase the throttle to a point where it boggs and dies. Sometimes I am able to feather the throttle back and and then VERY VERY slowly work my way past the bogg point. If I can sucessfully feather the throttle past the bogg point it runs under load great.<br /><br />I have done the following: new fuel filter, fuel pump diaphram, carbs rebuilt by dealer, new plugs new gas, stabil in tank, new tank to motor fuel line. <br /><br />Suggestions???

Carbs would have been my first guess, if you are sure they are clean... I would test for compression and then spark, then timing.

The merc dealer who rebuilt my carbs has agreed to take it back and check them - I sure hope that's the problem. In the future I need to learn how to do the carbs myself as I don't plan on shelling out $400 to get it done ever again.
