may need CDI/Power Pack for 92' Yammi 150

[deshet]

may need CDI/Power Pack for 92' Yamaha 150. Took it in to have the carbs rebuilt and my friend says it is only idling on two cylinders. It is a V6 and he says it is only idling on the middle two cylinders. He is going to test everything out but I believe it is either the CDI/Powerpack, or the Stator. I doubt 4 coils went bad.

New Powerpack is pretty expensive. Should I go used? Does anyone have one forsale?

Just to make sure I have the right idea, a CDI is yamaha's version of a power pack.

I don't have the exact model number but it is a 1992 Yamaha 150 prescision blend 2 stroke.

Hour meter shows about 800 hrs

thanks
