I receieved my new Evolution/MVVS 26gx engine today. It did not come with breakin oil(my45gx2 came with break-in oil), can I use Amsoil 100:1 golden sabre at the 30:1 mix for break-in. Mobil 1 quit making 2T racing synthic oil. Does the slanted spark plug add anything to the performance? The engine is going into the H9 Sundowner and I plan to use the tuned pipe that goes with this engine. Is this engine different on break-in because of the piston and cylinder material? In the past I used Penziol air cooled 2 cycle at a 32:1 mix for the first 2 to 3 gallons and then switched to Amsoil 100:1 mix. This engine looks well made and if it is as good as my 45gx2 it will be a great engine.

Thanks,
