[6pack] carbon cannister replacement

[j.honor at comcast.net]

I am in process of replacing my valve coveron my 74 TR6B with new alloy from
TRF, used opportunity to check/replace hoses etc in inspection of carbon
cannister-had car 6 years never ever looked more than sideways, noticed the
gauze filter was fair condition-some carbob particles but intact etc. question
is should I replace? at Moss $88 a lot for questionalble value-car is running
well-fuel use/performance. let me know what you've done with this. Thanks-
regards, Joe
