I have put in a set of engine dynamics in my motor and the idle at the moment is pretty crappy (but neve stalls). Henk says the manifold presure at idle is too high, the car behaves odly from 1 to 2K rpms (it kangoroos and is veeeery weak) but afterwards it starts pulling ok. I had a play with another 172 and the difference is noticiable, not a chance to defeat me. E&D have the same spec as C&B, so hence the question, how is your idle, have any one metered the manifold presure at idle?
With cams the car seems to have a flat spot at 3.5K, I am running the first version of my map so I hope it gets better after fine tunning
Thanks
