Ed,

As Scott points out, NovaRossi has had some translation issues in their documentation. I addressed this directly with them (during a review I wrote on the Speed/13) and they agreed that the English could stand a revision.

ABC engines should be broken in as such as already mentioned by others. Jim's suggestion of pre-lubing the rod bushings is a good one. If you don't touch the factory set carb it should start and run perfectly. If you have inflight needle adjustment, you should be able to just use that to control engine RPM (i.e., rich first tank or two) during test stand break-in. The engines will swallow a 16 oz tank in no time during the break-in runs. My engine was running perfectly after half a gallon of fuel.

I used Omega fuel with 3 oz of castor added per gallon. Once broken in, you can reduce the added castor slightly but the engines are so powerful that keeping them well lubed is not a bad idea for longevity.
