I have had an ongoing problem
I have had an ongoing problem with the motor on our sailboat. When started cold it runs on what sounds like one cyl.and wont throttle up until this missing clears. I replaced the carb. as we saw indication of a previous owners attempts to do some magic. This had o effect. I pulled the head and inspected the bores and at this time had a good shop re guide the head as well grind the valves. Valve settings were done to spec and guess what.....same thing still happens. Once warm the thing is flawless but get up in the morning and try to get it started you may as well go back to the bunk cause it can take up to 30 minutes of low idle to make it smooth out. New plugs new fuel as well connectors hoses and tank all to no avail. Could I have a bad brain box or coil. What is the procedure and electrical values to test these. Yes I have a really good meter
