Mariner 90 Stalling

Hi, I have a 1994 90 Mariner, I have been getting it cleaned up and ready for the summer and I have come to a problem with the engine hesitating and stalling when I give it throttle from an idle. It has a new stator, pickup, regulator and switch box, plugs and I cleaned the carbs and installed kits in all three. Could you help put me on the right track to a solution for this problem.  



Not being there, I'd say you've done almost everything so far. The last thing to look at is the spark/throttle set up. Make sure the timing is advancing and the butterflies are not opening before the advance starts. This could cause the scenario you describe.

Also is the compression and general engine in good shape? 

Things to check.....
