Is a Suzuki built motor for Arctic cat before their Bankruptcy. That makes it 81 or older. Go to Browns point marine look up early Suzuki DT 25 motors.
Yup that is probably the cheapest carb kit you found and they are nothing but trouble. hopefully you did not force that in the hole, because more than likely the threads are wrong. Sideview shows 2 different threads.
They went to the bigger pump on everything later in the 80s or early 90s. usually used a reducing T on the smaller engines. a cost cutting measure I think.
They make a rebuild kit for those. Easy to do just watch out for the little springs. Pretty sure this is it. Stay away from the cheap chinese $20 ones they are nothing but trouble. A factory pump is $170 the rebuild kit is $16

Push the small lever up just until you feel friction. Push key in while starting. Be prepared to push the small lever down if it starts and takes off. May be some trial and error to find the right setting. If the small lever is up you should not be able to shift.
