My engine is knocking at idle. And it is getting louder with each autocross!
It appears to be coming from cylinder number three. The engine idles and there is no smoke in the exhaust. At higher RPM’s there is a loss of power and it is running rougher. I don’t think it is a carburetor or ignition problem. Is it cylinder or bearing knock? Is it time to rebuild? Hmmm? |

Try adjusting the valves and make sure you pull out the valve adjuster screws and look at them closely. About a year ago mine started making a knocking noise that I though was in the bottom end but turned out to be a worn down valve adjuster screw. It was brand new too but had worn flat. I guess that one didn't get the proper hardening or something. Swapped it out, did an oil change and it's been great since.
