measure the distance between center of driver to center of driven. Double check you have the correct belt.

Post a few pictures of your setup.
here is a picture of my problem where the belt gets caught in the pulley .

Just as I had thought, your driven is installed backwards. With the 40 series, the cam should be inboard (closer to the engine). I know some models (max torque?) can run with the cam outboard, but you need to change the spring around/get a different spring. Blaz should be able to tell you if that is an option with thee 40 series.

Precisely, just like the picture below. There is a chance you can just swap out the springs, but someone else will need to confirm whether or not that is possible with the 40 series.

Running a 40 driven in reverse orientation is possible, but you need a reverse-wound spring to do so.
The subaru ex27 engine is unbelievable fast!. Its a huge differeince in power from the stock tecumseh motor on the yerf dog 3203. its like going from a vw bug engine to a porsche 911 engine. lol. when I went up the hill it flew up there. I was shock. and thats with the Governor on it. I had yet to reach top speed on my 6 acres becouse I had to slow down to make turns and terrain is bumpy to. So I had to make sure all bolts were tight.

I have a manco intruder II and a aerforce f-265. they both run the driven with the cam outboard. The 265 is a EX27 with a 40 series. The reverse wound spring is yellow, and is commonly available.
