I have a 1976 evinrude 135hp that I rebuilt last summer. Installed new electronics and rebuilt the carbs. The motor runs fine at idle 1/2 and 3/4 throttle, but as soon as I go to full throttle the engine cuts out in a about 5 seconds, if I pull back the throttle to 3/4, it comes right out of it and runs fine. Any ideas on narrow ing this down? I shot I video of it cutting out, but it won't let me download it on here. email at thorw@charter.net and I will send it to you. Thanks
