Thanks for response. Shop had it running right nice and smooth.new fuel pump, water pump, carb rebuild, Lync and sync, and it ran good for a couple days. Few days later, it wouldn't start for anything. Took it to a merc certified mechanic and the dva readings were bad and had weak spark. He told me to get a switchbox. I got a switchbox put it on, still hard to start. I investigated and found the kill wire had two volts so I unhooked it and it fired up. But it was idling super high so I stuck a timing light on and it was at like 20 after tdc so I adjusted it back to 6 before tdc which the book says and still idled at 1800. Idled high no matter we're it's at.
