Any comments to confirm or dismiss (with proof) would make it very informative to people considering picking this engine up
You asked if they were the same engine and a lot of other questions (bearings/ignition).
I have attempted to answer.
You asked in the link if you should run synthetic.
You were told you should.
Mvvs say you should run MX2T and give you some to start and then High quality Racing synthetic.
Evolution say the same.
You choose to run SEMI synthetic and take a loose test to support yourself.
You still havent said what prop your running.
You still wonder where you have lost 1000 rpm
Or are you talking about some other engine now.
See ya
