Please bear with me me as this is my first post. I have a 50hp 2 stroke that is surging or acting like it is fuel starved at WOT. If I squeeze the primer bulb it will run with out an issue for about a minute. It will also run in netrual at full rmp. I havereplaced the plugs rebuilt carbs, checked compression 120 across a four, replaced fuel line, tank, and cleaned internal lines. The I have also checked timing and idol mix as well as check spark.
I am stumped but am also to stuborn to bring it to the shop and with a new baby in the house can scarcly affordable it and my wife is running out of patientance.
Any help would be greatly appreciated
I was going through the manual and started checking the electrical side and got a high reading on the strator blue and blue wht wires could this be the cause of the surging at WOT?
