B&S 13.5HP 28M707 inlet valve retainer replacement

[PaulD]

I am re-assembling this engine after a seize up and have lost the key-hole intake valve retainer 690656 which is no longer available. Are any other b&s retainers suitable or should I use the exhaust valve keeper and retainer?
The replacement inlet valve has a different fluted bottom section presumably suited to fit the key-hole. Does this require a different keeper?
There are a few available 690656 available on line in the US that cannot post to Australia.
Any suggestions would be appreciated

Contact bertsmobile1 in Australia by clicking on his name this website & see if Bert has retainer for intake valve for sale.

Thanks Mark
None of those sites have the retainer as it is either discontinued or they don't post to Australia.
My question then is do the split keepers for the exhaust valve fit on the inlet valve? I have had another look and both the new and old inlet valves have the same profile.
