I've gotta say this clutch side seal setup on the 372 is much different from the 394. I put in a new seal, o-ring and oil pump driver. I got it started and it would rev up good, but the idle was off and it would stall. There's a big thunder storm going over right now, so I didn't go outside fuss with the adjustments, just ran it the way it came. I'll work on tuning tomorrow hopefully. I don't know if I got the seal in right, there isn't much room for error. The little o-ring didn't look great, but I don't think that has anything to do with the seals failing. All OEM parts.
