i got those new blower shop 750's from here for a great deal but before that i was watching ebay and depending on your budget there are an older pair of 750 blower carbs with choke horns still and all that for $350 on ebay right now and holley blows out refurbished aluminum 750hp blower carbs for about $450-$475 each which is a smoking deal but they only put one up at a time so it might take you 3 weeks to make up the set that way.
also ebay for the pulleys and belts...$100-$150 for what you are looking for.
did you buy that blower from the guy in gardena off craigslist buy any chance?
