I think carlson may have the bulk of the worlds present stock of the mpjet .061 engine, as the son took over the factory and they began producing electric motors. But I asked mr Carlson and he said the tooling is still there if the need for another batch run of the engines happens in future.. Sort of the same attitude cox and va seem to have taken..
Anyway, have a look at the mpjet, it weighs more than the norvel, but it may hold together better since it's sold as a diesel too, and beefier as a result.
Please ignore the above post- it's off topic, sorry.[
