for rebuild kits I just got my order from cheaponlineparts.com I'd used them about a year ago and they were about 2/3 the price then (or 3/4) but since I've never gotten a rebuild kit for a zama I got a few (I have too many of the carbs that aren't usable because of bad diaphrams to not have parts around). Their part number ROT9199 is the most common weedie kit and is $5.29. walbro kit for $4.79, just the metering diaphragm for walbro is $3.52 (that's about all that goes bad on many engines, so I grabbed a handful)
