I bought a Saito 100 about a couple of months ago for my P-51B Mustang...mounted it the plane ,only to find out that there was no compression..returned the engine to Horizon and they mention that there was balsa dust in the engine,and they corrected the problem...well I got it back,mounted it the plane again,only to find out that it was very hard to turn it..there was no free wheeling like normal engines do,so I mounted a prop on it and began to tighten the prop nut up,and there was a loud 'Bang", like something broke inside...I took the back cover off,and found no shavings or anything that cause this loud bang..I inspected the engine from front to back, and found nothing broken...the engine now is freewheeling and plenty of compression..Bearings were mention in this thread,and I wonder if that might of been the problem as to the engine being tight, and not free wheeling..Never had a Saito that acted like this, so maybe this week,might try to start it up and see what happens..Know one thing...as soon as it starts, am moving to the back of the engine,just in case this engine goes bananas..will let you know what happens....
