A word of caution is fine but this was virtually outright saying the work would be junk and was bad and the worst idea ever, in a nutshell.
Carb dip costs next to nothing with as much as it can be used before it needs to be replaced. Maybe for this guy, carbs are a nice side job as opposed to rebuilding a blown engine re-wiring the electrical system.
As for sending my carbs, A: my bike is in storage for the winter. B: I distrust the postal and even ups system more than some unknown mechanic. And as this mechanic is in his area, it is not the great unknown. So again, a word of caution, fine, basically saying someone is stupid for even thinking it, not fine. Kinda like chewing on someone cause they want to try and modify the electrical system, eh tt.
