65 C10 250 stock..high frequency pure tone??
Runs as it should.. no other issues that haven't or will be addressed
It just started The tone doesn't change with RPMs If I pull throttle down to 5-600 it goes away But just start and hear it Does it regardless of sitting at idle, driving or shifting..etc.. Does not change pitch with movement of clutch or higher RPMs ??? Can't think of anything that would make the sound and Not change at all really with Any changing of anything |
