Hello!
I have a 1993 model Johnson 521cc. It's the 20hp model, but carb has been changed to a 30 hp one.
After last winter I've got some starting problems..
starts actually easy on 3rd or 4th pull, but then it coughs and stops. Another pull, same happens.. this keeps happening a few times, then it starts to run on idle.
Full throttle runs fine, pushes boat fine, when slowing to lower rpms, doesn't want to run.. it doesn't shut down but almost seems to do it.. like at times it's not getting enough fuel.
So where to start to fix this? I'm not a mechanic but can do most basic things.. these engines aren't that complex.
