Hi Guys,
Charlie your memory is pretty good despite the time gone by. Yes, I
did post a message a while back about the engine pinging under load. I
just began runing slightly higher RPM's and that seemed to help. I'm not
too crazy about the idea of pulling the heads, and I'm not sure I want
to go squirting water into the carbs at high rpm either. I guess I'll
just try the hard acceleration/decelleration trick some time over the
next few days. The only thing I've noticed is thet the left plug has
some slight carbon deposit like it might be runing a little rich on that
side. Ohterwise the old girl runs great, no problems. Yesterday I took
her out to the north fork of Long Island (2 up), put about 250 miles on
and had a great day.
Thanks for all your input!

 Hi Mike and all,

Seems I remember a few weeks ago Vince posted a message about having
pinging problems, this may be why.

Anyone ever tried the "steam cleaning" trick to remove carbon? Water
vapor is introduced through the carb. or other inlet opening while the
engine is running. The idea is, I guess, that the water vapor turns to
steam in the combustion chamber and removes the carbon. Never done it
myself, but an old-time shade-tree mechanic friend of my late Dad swore
it worked. Cheers,

Charlie

 Agreed....pinging would also be a problem if it was too high...side to
side
is the most important.

 If it is running well leave it alone, 190 is fine ,allowing for slight
innaccuracies in Bourdn tube pressure guages you should be in good
shape. I have seen a few GOOD non carboned engines with pressure in this
range. More importantly they are EVEN from side to side.
You have an excellent ring seal , Good valve to seat contact and a
guage that may be reading right on the money to a few pouds high. The
side to side readings are real good and if the engine shows no signs og
the kind of problems already mentioned regarding knocking etc,it is best
to enjoy !

 Today I checked the compression in my Eldo. Both cylinders read 190psi.
If my memory serves me well this is a bit on the high side. Does anyone
know the proper specs? If it is too high, what might be the cause?
Thanks........ Vince in NY



Is that the single malt talking or just another cheap WHINE ?
