As you will recall, In our last episode, I was preparing to install the
new starter in my Merc. 5.0. I did a compression test with the old
starter in place, 150 all around. After sitting 2 weeks, the new starter
is in; I cranked it with the plugs out (no manifolds installed yet) And
it spun 3 revolutions with a *Clack* every 360°. I thought in this brief
time that possibly a tooth was sheared on the flywheel ring, but after 3
revolutions the engine locked and would not turn. ****. I was thinking
maybe a socket I had holding the Qjet choke open had somehow fallen into
the intake manifold and wedged an intake valve open. Ok. I put a chain
wrench on the balancer and found I could rotate the engine backwards,
but would lock at the same point forwards. I pulled the valve covers,
expecting to find an offending intake valve hung open, with slop in the
rocker arm as a result. Found it, alright, but an exhaust valve, not
intake. Feeling up the #4 exhaust port with my finger, I can feel the
broken end of the exhaust valve stem. The valve head is loose in the
combustion chamber, preventing the piston from reaching TDC. DOUBLE
****. In the 2 weeks since the compression test, the #4 exhaust valve
seized in the guide, and on cranking, because the valve is at an angle
with the piston, was broken off. Now I get to pull the heads......
Oh well, the engine is 18 years old, has 495 Hrs on it, and with all
that down time, a seized valve is not unusual.

Man, that's quite the saga, but that's the way it goes sometimes.- Hide quoted text -

Hey loog-meister, I know you don't need one, but just for the fun of
it I called about the price of a brand new starter for your v-4
(85-115 hp.) Evinrude and it costs me $51.00 + shipping not bad, eh?
