Ed,
On my engine, the coolant wouldn't even circulate because air was =
trapped in the water pump impeller area.  Since I've modified my wp =
housing to eliminate the thermostats, I now have to remove the coolant =
pressure sensor on the side of the housing to allow the air to escape.  =
So, you must verify that the coolant is circulating (put hand on =
radiator hoses...they should start getting warm very quickly), or else =
shut it down and find out why it is not circulating.   =20

Good advise, Mark.

I did overheat an engine early-on due to entrapped air.  While I have a=20

even in the automobile, several burping of the engine is recommended.  I =

this by carefully watching the engine temps and running the rpm up to =
around=20
4000-5000 this appears to flush the air out of my evaporator cores (they =

entrap approx. 1/3 their volume in air each time I drain the system - =
which=20
must be flushed out before attempting flight (or extended engine runs).  =

Bob,
You probably know this, but be sure to bleed the air out of the block =
before=20
running the engine for the first time.  That usually means removing the=20
thermostat so the air can escape through the bypass circuit.  It would =
be a=20
shame to overheat a new engine due to low coolant.  It has happened more =

than once, and almost happened to me.

Good luck,
Mark S.

Any of you who have read my signature would know that I was trying to
get my engine started by today at the latest.  It didn't happen.  I
have a long list of excuses, but I won't bore you with them. :)

I am still plodding along on the wiring.  Once that's done, all that's
left is to tighten up some hoses, add fluids, do some system checks, and
give it a try.

From the land of ma=F1ana,
Bob W.  (Sorry I'm not making some noise!)
