The 790562 doesn't have an ACR on it, provided the online images are correct.

Now the one that the shop was thinking about is probably the 793880 camshaft on the 28, 31, 330000 series that does have an ACR that is prone to failures and it can take out the governor.

Any way let me know what you find to be the problem as it might something I need keep in mind if I run across this.
