For various reasons, I'm removing the carbon cannister and associated piping from my 1973 TR6. I've already gone with a vacuum advance distributor in place of the original vacuum retard. A few questions; (1) Do the fuel bowl vents on the Strombergs need to be maintained or can they simply be capped? (2) Is it a good idea to simply run the crankcase vent (from the rocker cover) straight to the original carburetor ports and capping the line that went to the carbon cannister, or could performance be enhanced by capping the carburetor ports and running the crankcase vent to something like a puke tank? I know the carburetors provided a slight vacuum to assist crankcase ventilation (hence the term PCV?) but is that really necessary?
