Nice to have my oil pressure sending unit (new) working right. But i discovered something while letting it idle and watching the gauge come down from 50psi cold to 40psi warm. I'm feeling a strange vibration in the steering wheel that changes as she idles. My first thought was not a good one: Bent crank,but would'nt that have self destructed by now. Or could it be that the carb needs a rebuild to meter fuel better?? Lots of questions so little answers..yet!
