Hello Ty;
     No, I was trying to avoid those because .049s don't use much fuel anyway, along with the extended fuel mileage that diesels get anyway, they might be making and mixing way more fuel than they could use in a a class room setting. I'm thinking a larger engine would just be better for them to handle and operate and use more fuel. I am starting to get an interest in little diesels and wish I had this urge while Jim Thomerson and Jim Wilson were still living. Two walking and talking encyclopedias on model diesel engines! I have acquired several small diesels and I may still take you up on it for my own enjoyment and may get back to you!
  Thanks a lot,
   Dan McEntee
