<DIV><FONT face=Arial size=2>It not just a matter of swelling with a YS
silicone diaphragm. If they go soft and spongy they also behave badly. A tip
- you need to look at the diaphragm immediately after you remove it
from the motor. If it is "belled" or distorted you could well have a
bad one. I said immediately because they go back to a flat shape quite
quickly when not inside of the pump.</FONT></DIV>

face=sans-serif size=2>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 face=sans-serif size=2><BR><BR><BR>Gray

face="Comic Sans MS" size=3>You may be aware most of us down here mix our

have added 2-3% acetone into my fuel mix ( I buy pure Methanol) and I'm
