I have a 30 hp tohatsu that when put in gear it dies,when idling it has a little miss to it and rpm go up and down at idle. you can get it into gear but the rpm has to be so high that I know its not good for it, but when you get it in gear it will run good at topend.so far I have replaced fuel pump ,carb spark plugs ,filter ,fuel line,fuel and upper crank seal and oring.both plug wires will jump a 3/8 gap with a blue spark but when I set the testers to 7/16 gap as per the manual it will only fire on one.this model has the cdi/coils in one box.any suggestions thanks
