hey guys im new to the site, i have a 1990 70 hp johnson outboard the im having trouble starting. i just rebuilt the carbs, new water pump, thermostats, plugs, wires, and head gasket. when i got to start it it will crank and crank, when i put my hand ove the carb to cut air off and richen it will fire up but not run for long and occasionly it will seem like the rpms just randomly jump up and take off. if i could have some advice that would be great.
thanks, Dan
