   Jeff,
    You might keep an eye on the plastic hose goinng to the bottom of your
expansion tank..........This particular hose is not durable and under the h=
igh
heat under the cowl (perhaps not during your Canadian winter) might have
a short service life..........Project looks great and am looking forward to=

further flight test info..........

Thanks to you all for the congratulatory comments =E2=80=A6 attached is a p=
icture of expansion tank and preflight roll-out =E2=80=A6 the orange line i=
s fuel return; the brass is pressure gauge pickup and snifter valve install=
ation.
After reading Eds=E2=80=99 email I now know why the water temperature was s=
o high.  I installed a thermostat with the onset of cold weather, but I cou=
ldn=E2=80=99t use the original Mazda thermostat because my temperature bulb=
 protrudes across the bypass hole.  Originally the bypass hole was plugged =
and there was no thermostat; however, I removed the bypass plug and used a =
non-Mazda thermostat !! =E2=80=A6 so that=E2=80=99s why the underside of th=
e Mazda thermostat is so long! Thanks Ed for setting me straight and based =
on your comment about 20% loss of efficiency, I could possibly see 230F x 0=
.8 or as low as 184F on next flight =E2=80=A6 that would be great! For now =
the thermostat is gone and bypass is re-plugged.
Closer examination of the belt and rubber deposits on underside of top cowl=
ing suggests the belt got jammed in the pulley and cut by friction.
I tried again last night to remove the alternator pulley nut =E2=80=A6 what=
=E2=80=99s the secret? Left-hand thread? Loctite or what? It=E2=80=99s so t=
ight I=E2=80=99m afraid of damaging something trying to get it off.
