new old stock parts and number change questions

[pan breaux]

i'm looking at some NIB old stock power packs for my 8hp. mine has the original part number and i've found both of the succeeding part numbers. are the later part numbers different internally? should i be looking for the latest version only? i also found some aftermarket packs without a rev limiter for half the price, but not sure of their risk factor. has anyone had success with them or another version without a rev limiter? i'm not looking to go any faster, just looking to save some money.

Rev limiter is not needed for most applications.

Thanks, I doubted it too especially since I seldom run it fast enough to plane out. Right now I'm swapping the whole mess out for my diy "clintonstratton" so I can get some water under me.
