5 stars for headgear and 2 stars for Hondabond. After adjusting the valves on my Honda lawn mower, I replaced the head cover with these; Original part, fits perfectly. Big. After two days, look at the mower and you will see a puddle of oil where it is leaking from under the replacement cover. Remove the cap, remove the Hondabond, reapply a new coat of Hondabond and this time there is no leak. Things are dirty. Will be looking for a Permatex product for my next replacement.
