I just replaced my 196cc engine in my Coleman with a predator 212. Long story why. Anyway. I got it all together and ready but now it immediately grabs the belt. I can’t even push the cart because it instantly grabs. When I start it it also revs and tries to go. I did notice that the screw with spring in the throttle assembly is half screwed in already. On my old engine it was backed out all the way.

I tried to mess with the idle screw but it did nothing

What changed? Do you need a different size belt now. I thought it was all a direct swap
