Yesterday, when rebuilding the three carburetors on my 79' Johnson 175, I noticed that the top one has a 1 inch venturi, while the lower two have 1 5/16 inch venturis. The lower two look like they were replaced by a previous owner. Does anyone know if all three need to be the same? My shop manual doesn't specify venturi size.

Check with your local Johnson dealer but I think that the 175 had one carb that was larger. I can not remember which one.
