So did mine lol. I had to drill 4 holes through both of those rings at the seam and rivet the thing together. 1/4 smooth rod and a hammer hasn't come off yet. Also added alot of pock marks on the aluminum with a punch.

I am returning this kit to seller. What would be a better kit to buy. I was looking at the 79cc kit is it any better than the 142f?
