it kind of bogs down until shuts off, loses all power and sounds way different then normal, just cutting off aint soft seizing and lack off oil will cause a soft but going by the sight of smoke from the pipe isn't 100 percent either, neither of my 2t smoke from the pipe

I had a bad seize and it locked up the rear tire . I had it softseize twice on another engine but it fired up after it cooled no problem . Soft seize is when your running too lean like too small of a main jet or too much oil . Pull out yoursparkplug and compare it to this chart to get an idea on how the jetting is http://www.4secondsflat.com/plug_chart.html

50:1 sometimes gives problems, I had the same oil for my mopeds.
They recommend 16:1, but in reality that's too much oil. Most people use a 32:1 ratio. Using 50:1 generally causes more engine wear. |
