Or the *ORIGINAL EQUIPMENT* cat on my carbed '82 Mazda 626 which, due to an uncooperative electrical fault that took the better part of a year of on and off hunting to finally pin down and cure for good, got push-started on a fairly regular basis - Sometimes as often as 4-5 times in an hour during a 4-8 hour shift when it was earning its keep as a pizza-mobile. On November 30th of last year, it went through California smog testing showing less than 1-3 of the allowed emissions for its testing category - *ACROSS THE BOARD* - and WITHOUT needing to resort to any of the "fool the machine" tricks or gimmicks to make it happen.
Needless to say, I ain't sweating even a little bit over zapping the cat with a push start, regardless of the dire warnings that folks like Kaz keep tossing out.
Absolutely. Continuously dumping raw fuel-charge into a cat is gonna turn its innards into a heap of fused slag in short order. That would be one of those things that fall into the "unquestionable fact" category. The few snorts of fuel-mix it gets from performing a proper (IE, key on, get to speed, then dump the clutch in second or third) push-start on an otherwise healthy engine don't amount to a half-butted fart in a hurricane.
