My .46NT and .455PTS are strong engines that run extremely well. I had a model with a TT Pro .46, OS .47FX and the NT on it. The Evo was a far stronger engine from the first tank of fuel.

Your new engine may have a tight pinch. Mine squealed when I tried to turn it over by hand. Also, you can use the installed glow plug for that first tank of fuel, but I would strongly recommend that you replace it with an OS A3. These engines seem to need that hotter plug, and that also includes the .40, .61, and 1.00. I don't know about the .36. It should loosen up considerably after about 10 oz of fuel.
