Got lucky since I work at a small engine shop and picked up a clutch for a Toro Workman (kinda like a golf cart) (model 07273, part number 108-7013, if someone wants to look at a diagram online under "Toro Parts") and it is for a Briggs and Stratton engine with a tapered shaft. I'm trying to figure out which clutch this is. I think it is a Comet clutch, it's a 7 1/2" diameter, it has 363 and 390 both inside a circle that is cast into the main body where the arms attach. I took 9 pictures of it, just trying to get someone to resize them for me so that everyone can take a look and hopefully help me to identify this clutch. If it is at all possible, I would like to run this clutch or one very like it on a Kohler CH740 engine in a dragster. Any help and/or suggestions would be a great help. Thanks!
