There's still chunks of aluminum in both the ports and a major gap under the top cylinder head! This will cause low compression and restricted air and fuel flow !!

I’m writing this review cause it my first time buying it and it look pretty darn sturdy and looks like it can hold up a good fight for what I’m about to do to it!

Everything seemed good until it wasn’t had an even broken it in until the head bolts broke loose. The whole entire stud that goes through the engine pulled out of the engine block because of poor machining or poor tapping on their end in order to fix it I have to re-tap the block and put a bigger stud, and luckily it allows for room for the bigger stud.

Magneto wire + and - cut. Have not installed it yet so cant speak to performance. I can easily fix this issue which is why I am not sending it back unless something serious turns up in operation. Cant help but think QC was sleeping when my item was shipped. Will post a second review of its operation after I fix and install it. (Edit after install). Works decent after fixing factory errors. Still in break in process so final review pending. (Edit after break in). Decent motor. Not the best but not the worst. Pairs best with a 28 tooth sprocket on a OCC Schwinn using bike berry mounts.
