I don't have Ruggles's book handy, but can try to find my copy if you don't get any better answers to your question.
did the book talk about cleaning those ports where the tubes came out of ?
the guy i talked to said ( just because air and carb cleaner goes through the idle tubes that doesnt mean theyre cleared out, they become "corrosantifyed" and plugged up)
also how did u install the new tubes ???
