If that is true, at least that would be a permanent fix which would never need to be regreased or fiddled with again
Don't believe everything you read. If the vacuum ports were a bad thing engine manufacturers would not take the time or spend the money to have them in the engines. I would think Novarossi among other manufacturers who have been doing this since the invention of micro motors may know a bit more than some guy with a Dremel
