    use hi octane petrol mixture along with super petrol
    make sure your plugs are gapped properly

    then please go n get the gapping checked from a mechanic, he most likely messed up gapping of plugs resulting in knocking.

    poor fuel will generate knock,... so will bad timing, poor sparking, etc.

    Maybe the valves are eroded due to bad fuel.
    Age is a very high price to pay for maturity.
