Michelle;There are still some unknowns.First of all, the 40% you refer to is most likely a combination of cocoa beans and cocoa butter. Even if the maximum amount of lecithin is used (and at the right time) in the manufacture of the chocolate it will be very, very thick - most likely too thick work in your fountain.Lecithin in the manufacture of chocolate can play a double role - it can either thicken the chocolate, or it can thin the chocolate. The percentages used in relation to the batch made at the factory are in fractions of one percent by weight. If that fraction is too high, even by 1/10th of one percent, it could thicken the chocolate and cause you the grief you are experiencing.In the case of the chocolate you are using, this may be the case - a slight miscalculation at the factory.The chocolate I make here at Chocolate, is a 48% (17% cocoa beans, and 31% cocoa butter) and it still needs to be thinned out for a fountain.Furthermore, with a 40% milk chocolate you may not be getting enough "chocolate" flavour. My recommendation would be to thin it out with a combination of cocoa butter and a strong 70% dark. You will still get the milky chocolate, but a slightly stronger chocolate flavour.Also, by using cocoa butter, the chocolate will crystalize again once cold, and store for future use with the fountain (if you are so inclined to do so). Using cream will cause it to spoil at room temperature, and using another oil (vegetable oil is common... Yuck!) will also give you grief, as vegetable oil also goes rancid in time.To thin it out, start with increments of cocoa butter, 5% by weight, until it's thin, and then add some dark chocolate to bring back the chocolate flavour.That's my 2 cents for what it's worth.
