zama vs tillotson ms250 sthil saw

[sawdust_wizard]

just wondering is there a carb better than the other? which one last longer or performs better. I got a stihl 025 I came across it came
C1Q-S76 zama carb. I see tillotson makes hu131a carb as a direct replacement through the tillotson xchange web page just wondering peoples thoughts of changing to a tillotson carb

I've never run a Tilly on an 025/250, but a WT215 is cheap, fully adjustable and runs great on those saws.
