Finally got the S1 to start after engine rebuild and efi conversion, engines had crank regound, new mains and big ends, block rebored and honed, new pistons, gaskets and oil seals. Engine had a brand new Burton oil HP oil pump fitted as well, Oil pressure light was out at initial start up, but once the engine warmed up the oil light was flickering, did not notice straight away due to having to work the throttle from the engine bay. I removed the oil filler cap and the inside the rocker cover was dry. Any ideas ?
Thanks
Pete.
