Walbro carbs

[Danrox90]

What is the difference between the stock 668 carb and the 997 carb.
Thanks

Have seen several carb. numbers, but 997 is not one of them.
Where did you get that number ?

Really? http://www.gizmomotors.com/index.php/online-store/walbro-carbs-parts/wt-997-walbro-cab-detail There is a link to one...

" Description

5th Scale RC Car Walbro 997 (same specs as 668) "

The quote is from that link.
This one is news to me, but must be a newer replacement for the 668.
If you question it, I would call Gizmo, and personally ask.
