90% of my motors are Nelsons or Jetts.

You are right about the threads being the same, but you don't know if the needles are the same length or the threads start in the same spot. You also don't know how sharp or blunt the needle is. Opening it 3 vs 5 times from closed is no big deal, I just prefer to err on the rich side.

I have no doubt this motor will run, and most likely well, but its not even a close comparison in terms of fit and finish to the motors I normally run.

I think it is a very neat motor and I look forward to building a plane around it, so I am not knocking it.
