I've never seen a Talon with a thrown rod.

18 inch cutting width Talon and a 19 inch Talon from what can see.

Checked a few motors and I got the same as Tyler 65mmX48.7mm

I've put Briggs on Talon Mowers and Talon engines on Rover mowers if you compare 18 with 18 inch but one mower engine is
the Talon and one is the Briggs ,I don't notice a difference.

Never done a starting load test on the mowers though .
