1987 Johnson 120 VRO Running Good Now

I spent an entire season troubleshooting this motor and finally got it all worked out. There was more than one problem so troubleshooting was a pain and had to just keep replacing things until it ran good.
I remember I had problems with the jets in the carbs, problem with timing advance (timer base), problem with power pack, feul pump was weak and even an air leak in the fuel line. When you get multiple problems like this all at once it can be very frustrating to figure out but rewarding in the end..as long as you keep your sanity that is...lol
