Motor runs great at first day start up, drive 8 to 10 miles not a burp. Start again 2 hours later and motor runs great at first and then misses. Sounds almost like not enough fuel or air/water in gas. Slow down and it runs good again but get to higher RPM and then coughs. Try again and then...
I have a fresh rebuilt 1994 Johnson 120 V4. It runs great at top end and idles beautifully, can even troll with it and it just hums. But when I travel at slow speeds between 1000 and 2000 RPM it stutters quite a bit but doesn't stall out....what could this be? Thanks in advance for any input.
