I also heard that gas refineries do something to the gasoline in the winter
time. Check your O2 sensors. Don't know much about you MP-SK250 TB either.
I'm assuming you had all these mods before the weather got cold and didn't
experience any problems then? What are the plugs gapped at?

Thanks Walt
That was my first thought also, but the engine warms up to approximately 180
and I can watch the t-stat open by looking at the temp guage. The temp then
holds steady at approximately 180..... I've got a replacement t-stat ready
to
go in, but I don't think that is the problem! The other weird thing is that
I
don't get a mil light or anything even after it misfires!?!
