I really can't believe I haven't cracked my stock engine plate. I have flipped that thing on the head so many times but still haven't bent the Plate. Lol. Yeah the collari was a high dollar engine in its day. Italian built. I bought it 2nd hand for 35 bucks but I don't think it had ever been run. I ran a break in on it and it has good throttle response, idles great and has pretty decent Power. Can't complain for the mOney.
