Chainsaw Repair

I've used both brands on the 55 either works well.  I like the Walbro because the WAT kit is cheap and fits a lot of models inc Stihl.  One note the af housing for the Walbro is different than the one for the Zama.  Zama housing will work with Walbro carb.  Walbro housing can be made to work with a little grinding.  The length of carb adj. screws is diff.  Walbro shorter than Zama.
