I have a 5/8" spacer between carb and manifold. Is this necessary and what is the advantage , if any? thanks, andy
Spacer Andy, I do believe it acts like a insulator, keeping the carburetor cooler and the fuel from evaporating prematurely. This is accomplish as it isolates heat transfer form the intake and exhaust assembly. My three cents.
Carby Insulator I assme we're talking about a 235 here ? It's *very* imporant . Once in a while the original ones will suddenly develop cracks , not to wory , just buy a new one and remember : NO GASKET between the insulator and the intake manifold , only between the insulator and the carby .
Carby Gasketing No worries , just hang it on a nail in the shop , you'll be needing it sooner or later . FWIW , always try to use the very thinnest gasket you can , this will prevent leaks , weeps & seeps from developing later on . In Carbys ' thick gaskets cause vacuum leaks . Of course , the Rochester 'B' series carby you have , needs those four slots cut in the base gasket to provide vacuum for the power valve .
