Chainsaw Repair

Cut4fun, ... I checked out your links ... quite honestly, I never considered looking on EBay, as I guess I am old school and do VERY little shopping online. Have you purchased parts from any of these people? Can their ratings be trusted? Is Paypal kind of a neutral fund collector? I really prefer my bank information stay private! ... As you see, there are concerns with this type of transaction!

I didnt look at sellers. Just the 3 lowest prices shipped. 
Since you dont PP.

This is a Tillotson Exchange brand repair kit that replaces the Zama RB-19 kit (RB19). Zama discontinued this kit a number of years ago and we now offer these kits in the Tillotson Exchange line. This kit is used on McCulloch chainsaws with the Zama M-7 carburetors found on the models listed below. Note that these saws also use a Walbro brand carburetor, so be sure of your brand before you buy.
