YUP!

Old shade tree mechanic trick from back in the old days when the
antique gas was a real problem . The trick was to warm the engine and
squirt a few shots of water into the carb while holding the engine at
high rpm. never heard of any problems getting water into the float bowl.
It doesn't have much choice but to go on into the engine. If you've
ever seen a liquid cooled engine where coolant has seeped into a hot
cylinder you can see how effective it can be.
I would check ALL the other potential sources for pinging before
popping the heads. You can get a ggod llok thru the plug hole.
Unless the carbon buildup is massive MASSIVE! ,it does no harm. Carbon
buildup with modern fuel and oil rarely gets to the point where it
creates any concern.

 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 ?
