The carbs have been cleaned twice as a result of little usage. Now, I need to know how to do a complete, through tune-up, as the thing keeps dying at idle; idle speed hard to adjust without other adjustments; idle speed together with about three or four other adjustments were just done, and now the thing still doesn't want to idle without repeatedly going dead. I would like to learn how to completely adjust this engine as it ran just fine when new. The service manual doesn't offer much in the way of a complete tune-up. Thanks for any help. IraO

did you drop the carbs, soak em in carb cleaner, blow out the passages with compressed air? cant just blow cleaner thru em and say they are cleaned! that gummy crap is everywhere, and idle circuits arent too big
