Briggs OHV valve adjustment
I picked-up a nice looking White 1500 LT a couple months back, with the beginnings of a disassembled motor (just the tins and the ignition pick-up coil had been removed) and was told by the PO that it "wouldn't start". After some basic reassembly, I could see that it wouldn't turn over, much like a weak battery. But, the motor was free and it would spin without the spark plug installed. I thought it might be a valve adjustment issue, and as it turned-out, was a little deeper than that. It had a pretty badly bent exhaust valve push rod, and a destroyed push rod (plastic) guide. Recently, I thought I saw a pretty good video on MTF about adjusting the valves on a Briggs. I can't seem to find it using the search function, though. Can anybody give me the procedure and clearances to adjust the valves on this motor?
Model number on the motor is 28s777-1142-E1. Thanks for any help.
