: mM valve on the exhaust manifold heat riser
: will not open all the way, goes about 75 %
: open, most of the time. sometimes it barely
: opens at all. well i turned it to the spring
: steel stop and the stop broke. i am trying
: to find out why my eng runs so hot. it is a
: fresh motor but my other one ran hot too. so
: it's either that thing or the carb.can i get
: a whole new spring kit for the valve? and if
: it only opens 75% some of the time would
: that be a good guess for my heat prob?
: and.... should it remain open when the eng
: gets to temp or should it go back and forth
: with different throttle positions.. thanks

: I don't think this is the cause. I would take
: another look at the radiator, I have seen
: "crap" out of recently rebuild
: engines plug-up a good radiator fast. Are
: all the radiator "cores" (tubes)
: clear when you look in from the top? (drain
: the level down some and look.)
:
: Cooling is about water circulation and heat
: transfer in the radiator. With a big &
: efficiant (well working) radiator, you can
: cool just about anything.
