Another stalling problem with an Yamaha 75HP 2002 two stroke.

[delfinasul]

I have a two stroke 75hp Autolube 2002 Yamaha. My engine stalls when rpm drops under 1100. If i put in gear and push the throtle fast enought, the engine pass the critical RPM zone and run without any problem. The carbs are clean. I suspect one of the 2 coils from stator (the one with red and blue wire) because when i disconect the blue wire, the engine run smooth at idle and not die when i put in gear, but will no go over 4000 rpms. A strange fact, when i measured coil resistance everything is like in the service manual. Any help will be great. Thank's!

My stator partnumber is: 6H0-85510-03-00

Cand someone tell me, please, the technical data of the two stator coils used by iginition ? I mean wire diameter an number of turn, resistance, etc.

If it is not in service manual I do not think you will find the info
