Hello All,

I finished my top end rebuild and ran it few times over the winter. It ran very smooth the first couple of outings. Recently while warming up at about 1500 RPMS, the motor just died! After checking the MSD I found that it was dead so I replaced the MSD unit with a new one. Now it is running very rough, almost like it has a dead cylinder.....I pulled the plugs and they have a nice golden tint to them....

What could of happened?
What should I check next?

Thanks for the help!!!
