are the valve guides in a model 19 B&S replacable? does a 300421 use the same valve springs and retainers as a model 19? (model 19 and model 23 have the same part number but thats as far as my parts breakdown goes.)

30 CID engine has different P/N's for intake - exhaust valves and springs. Keepers and retainers hace same P/N. Parts book doesn't show any thing on valve guides. Neither does service book.

thanks, Bob. i'll cannabilize the retainers and collars from a spare 12 hp motor. i think the valves are salvagable but there was only one spring. at the Flywheeler show i met a lady selling B&S parts. said she has 2 warehouses full of NOS stuff. think i'll email her and see what she has. btw; she said she sells points for the 23s for about $40, because they are scarce. (last time i bought points locally, it was about $23. i never throw away points anymore!) just looked points up at jack's small engine- $21.76. still, i'll see what she has.
