Hopefully someone can help me. I have a 7/2002 130 HP yamaha that has aquired a high rpm intermitent miss. I paid a yamaha dealer to rebuild the carbs and the problem has not cleared. I have changed to several types of plugs with no result. I have changed out the coils with new ones, and I replaced the fuel line thinking the engine may be sucking some air. I still think the miss is a fuel related problem. Should I purchase some kits and try the carb thing again?

The first thing I done was buy a manual. I have completed everything to my knowledge that could cause the problem. Timing is correct, Air bleeds seem to be set accordingly. I was hoping someone had experienced this problem before and could shed some light. -
first try running motor under load WITH an auxillary tank.....and if you dont have them in, put the required ngk plugs back in and repost your findings.Comment
