Over heating -- cause found

[Henry Jay Hannigan]

---DON:
I extended my pipe on my 90 SP 36 also so my radiator stays clean!
An easy task; rubber hose and PVC to the hitch prevents anything
from getting into the radiator.
To me, the SP is an early version of the M380 only with a SIDE DOOR.
I have one cherry 90SP36 FOR SALE if someone wants a great coach,
ready to go with no 10-20K$$$$ to put into it...or if u know
someone who wants a "ready to go" 80FC31 with NO 10-20K$$$ needed to
fix it, then have them EMAIL me.....the 80 bird is with me in
Florida and the 90SP is chillin in Vegas...I am leaving for
AustRALIA IN late October. Hurry! Thanks.
Regards & LOL

PS the other day, I forgot to add Ralphs name to the "check out"
crew for anyone looking at a bird..sorry Ralph F.........also there
are other forum members capable of checking out a bird and giving an
opinion to a "NEWBY" buyer.
