84 115 missing

[hamburgerman]

I rebuilt the carbs. Pressure tested the fuel pump. New plugs. Did link and sync. Starts everytime, but runs rough at any speed. Dies at low idle after 10+ seconds. Fires right back up. Did spark test, looks like is sparking good on all, but all plugs are equally wet and oily when I take them out. I'm stumped. Power pack? Coils? Spent hours serching posts. Any help would be greatly appreciated. Leaving for vacation the 18th need help quick.

I gotta believe its still the carbs. You ight try advancing the idle timing just a speck.

Hook a timing light up to each coil. Watch it closely. Each plug should have a strong constant flash. I found one wire was intermittent. You could see the missed flash. Would miss every 5-6 rpm. Wound up being the power pack on that side.
