RE: Testing the new NV (Norvel) .40 size (6.5cc) gasoline glow engine
Mine was not that tight. They do say to rinse out the grease before you run it. I just put a little light oil in it to break down the grease. I will flush it and put a few drops of oil in it before I fire it up. It does seem tomhave very high compression, but that might change a little once rinsed out.
