<br><font size=2 face="sans-serif">Not sure of YS engines but most 2-stroke
engine pumps have a diaphram made of teflon coated glass, which is fine
with the acetone, but silicone fuel tubing will be deteriorated, as will
any othe silicone part (if any) in your engine. Viton will resist
acetone okay (o-rings). Big problem may be volatility as acetone will boil
at about 40C (note that I converted for your benefit) which is way lower
than the other components in fuel. If Acetone works and is not damaging
your engine seals (use gasoline tubing) try Methy-ethyl Ketone (MEK), more
expensive, much less volatile (one more carbon in the molecule). Next up
the chain is methy-isopropyl Ketone, which is a difficult product to obtain
in the USA at a hardware store....gotta go to Fisher chemical.</font>

<br><font size=3 face="Comic Sans MS">Gentlemen,</font>
<br><font size=3 face="Comic Sans MS">You may be aware most of us down
here mix our own fuel. We have available pure Methanol or a methanol product
'Shell A' which has 3% Acetone in it.</font>
<br><font size=3 face="Comic Sans MS">I have added 2-3% acetone into my
fuel mix ( I buy pure Methanol) and I'm not sure if I could detect a difference,
if any at all. It may have idled a bit better-but it could have been my
imagination??</font>
<br><font size=3> </font>
<br><font size=3 face="Comic Sans MS">So my question is-what exactly can/does
Acetone do in our fuel mixes?? Does it do anything at all?? </font>
<br><font size=3> </font>
<br><font size=3 face="Comic Sans MS">Thanks for any insight.</font>
