Model 19 Valves

Are valve guide available for the Briggs model 19 (200401-0019-01) engine or do I have to use bushings? Which bushings? Does the exhaust valve have the star on it? Thank you

    IPL lists no valve guides (bushings) for this engine. You need to determine if you have 1/4 or 5/16 valves and then use the appropriate brass valve guides (bushings) once the current valve guide are reamed to accept the new guides.
     
    Images of the exhaust valve show it to have a tapered section near the valve head vs the intake with no tapered section.

    Thank you. I have the 5/16 valves. Looking at the repair manual I didn’t understand which valve bushings I needed.

    From what I can tell the current setup is without bushings. The current guides are part of the casting.Now some came with a bronze replaceable bushing but this is not listed for your particular engine so it not likely to have these. This is easy to tell if they were used as you see it in the valve opening in the cylinder block.
     
    You need tool set 19232 to ream the guides to accept the brass bushings. Unless you are a shop this tool set can rather cost prohibited @ over $100 for one time use; it costed me $109 8 yrs ago. Even as a shop I have only use the tool set one time in 8 yrs for it intended purpose. Btw the Go/No Go gauge tool hasn't worked for me as I have seen 1/4 guides to pass this test and still be too worn to be usable so I assume it would be the same for the 5/16 version.
     
    Now the replacement brass bushing is part number 231218 per the service manual Chapter 6 page 7 (PDF page 177).

    Thank you so much. I have bushings 230655 which I assume are the same diameter wise just shorter and the valves fit the same in either the block valve guides and the bushing inserts (move slightly side to side) ?

    Either one of the two brass bushings would still need to be finished reamed to 5/16 as driving them in will slightly distort them plus using the pilot guide will help center up the finish ream job. Your new valves will still to lapped too as there still could be a slight mis-alignment.
