Phenolic Carb Spacer HELP

Yes, but it doesn't have to be a thick one. Make sure the carb is flat and a thin gasket will be okay.

Thanks Stubby, I presently have a fairly thin gasket between the carb spacer and the bottom of the carburetor, as well as a much thicker gasket between the manifold and the bottom of the carb spacer, but like I mention in a previous post, the instructions that came with a carburetor rebuild kit seemed to imply that a gasket was not necessary between the spacer and the carburetor. The instructions refer to a "Heat Insulator Block" which I take to be the same thing as the 'Phenolic Carb Spacer".????? Are they not one in the same??? Thanks, James

I believe they are referring to the standard cast alloy plate which has coolant running through it - it "insulates" the carb from temperatures much hotter than the coolant gets, and would stabilise its operating temperature somewhat in colder weather.
