meh my 81 RX-7 ran fine with all original motor with 89K on it
it sat for about 4 years, no one took care of it, started it or anything
got it running in about 1 hour, just replaced battery and fuel pump/filter and away i went
nothing comares to the smoothness of the rotary…i agree with yas on that, all the way up to however high that little 1.2 revved, was smooth as hell
