    Valve lash tolerance on 15.5 Briggs intek engine

    I was wondering if anyone knows the proper valve lash on a 15.5 briggs? I saw somewhere that the intake was a thousand or two larger than exhaust and i saw that both were set at .004 any input would be great. also it said set them a 1/4" past dead center past top. thanks

    Assuming OHV single cylinder then the valve clearance will be 0.03"-0.05 inlet and 0.05-0.07" for exhaust.
    Always set clearances with piston quarter past TDC on power stroke.
