I was looking over my motor and it seems my carbs are starting to weep from the bowls
I have read here that the bowls warp and they have aluminum replacements

Is this a simple swap ??? Can they be changed while still on The motor ????
I am pretty mechanicaly inclined and would like to save myself some money but on the other hand would hate to run into problems because I overlooked something, simple that a regular tech would pick up on

Just looking for some insight thanks
