B&S Intek 18.5hp ohv valve adjustment questions
31P777 SINGLE cylinder motor.
A few questions as I have seen many different "ways" to adjust my valves.
One way is to rotate crank until upper exhaust? valve is fully decompressed and adjust intake valve. Then compress lower intake? valve completely and adjust the exhaust valve.
THEN, I read to turn crank 1/4" past tdc on compression stroke (where neither valve is moving and both are fully closed) and adjust both intake (.004) and exhaust (.006) at the same time without turning the crank any more. This is because my motor has a compression relief valve on the cam.
Now for my questions:
Which is the INTAKE valve on my motor? (I am pretty sure it's the bottom but internet info has also said the top??)
Also read where the intake valve's pushrod is aluminum and exhaust is steel but mine is opposite??) what should each be?
