very high idle... bad distributor... engine

OK, thanks for the recommendations; I will investigate over the next few days.
(And sure hope its not the timing chain… although i guess this could be handled when doing the water pump, soon)
The Eleganza would also have this hot start problem at times, even with a brand new timing chain, brand new battery

So for this Birchhaven, we’re hoping for either slight timing adjustment, retarding it a bit, like Jim K suggested,
or maybe the heat shield issue….which is pretty interesting… and makes sense, having headers and all…
OK, Thanks again, and have a great weekend!

My suggestion to just retard a bit is based on the fact that he did not
have that issue before.

Update: I had a chance to do a hot highway drive today, and fortunately the slight distributor adjustment seems to have
fixed the hot start issue. I say “seems to have fixed” the issue, because the hot highway in Los Angeles today
never got over 45 MPH... the whole hour and a half journey. But i‘d imagine the engine was hot enough for the test (?)
and i have a feeling we’ve got the problem licked, thanks!

Ran pretty excellent overall. Idle was normal at traffic lights.
Learned a lot in the process (distributor refurbishing, tune-up, etc)
and if the problem comes back, i’ll definitely try the heat shield
thanks again!
