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. Mark

Good advise, Mark.
I did overheat an engine early-on due to entrapped air. While I have a "Plugs Up" installation which apparently tends to aggravate the situation, even in the automobile, several burping of the engine is recommended. I do this by carefully watching the engine temps and running the rpm up to around 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 must be flushed out before attempting flight (or extended engine runs). It would have been simply, IF I had just installed an air bleed petcock on top of each core - but, Alas back in 1995 that had not occurred to me {:>)

Bob,
You probably know this, but be sure to bleed the air out of the block before running the engine for the first time. That usually means removing the thermostat so the air can escape through the bypass circuit. It would be a 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 maņana,
Bob W. (Sorry I'm not making some noise!)
