Service manual describes synchronizing the carbs on 40 hp 4 cycle 2005, It mentions to remove all three intake plugs and install the gauge adaptors then the procedure. I do not have these special adaptors so I made one that works fine however my gauge pulsates so rapidly and with such a large travel it's unreadable. I installed a mercury manometer instead of the gauge and readings are obtainable however I wonder if perhaps the other two plugs should have been left out or if the special adaptors have a restricted orifice I should take into consideration. Any help would be appreciated, Lord knows I'm not shy of buying tools but I've adjusted many carbs in my wrenching days, don't see why these should be any different. Please if someone has these adaptors if you'd be so kind.
