i had a problem with power loss and was advised to rebuild carbs. i did this today and back on they went.seemed to run a little smoother and when i took it out it started to run a better than it was prior to rebuild, as if when i started it wanted to take off like it was running prior to the original problem then it lost power again but not as bad as before, if i pushed the primer in it would go a little more but if i sprayed premix into the carbs it would bog down till i did the top carb( 1984 johnson 70) after spraying into top carb it tried to get going, very noticable difference. thia was also the issue before that brought the suggestion to rebuild. i have 95 to 98 psi for compression, good spark and it runs fine at a slower speed. aggrevation is starting to set in and need help. i took the top carb off and took it apart and will be soaking it overnite. thanx, scott
