Starter Problem

Hi guys thx alot first!! The drive from the starter is going in into the end of the teeth from the converter gear! It was my thought too at the first time that i dont have enough battery power or something like that.. the cables are strong enough and the battery is from varta its also new, but when i bought the engine from a forum user here, he told me that the engine starts really hard, so i will try to borrow a optima battery from my friend, i do have a second starter but its the same problem its a starter about 90$ now i have a 3hp starter from ebay, that one:

I dont wanna spend another hundred dollars, but i have to find out what my problem is, and i will make a short vid while the engine is cranking, have to try that with a friend and i will let you guys knew what i found out
