Re: car stalls when stopping
Need more information.
Does the rest of your engine have enough mods to support a carburetor of this size and that style intake?
Have you tuned the carb?
Carburetors need to be tuned to the engine they are installed on
Sometimes you get lucky and one will work decently when bolting it on, but more often than not they need to be tuned.
Is your ignition timing correct?
