Hey everyone,
I've just installed a new GM crate 350 on a '67 c10. Got her started today and it's idling faster at 15 deg BTDC; when it's at 5 deg BTDC it seems to misfire and backfire through the carb (even runs on when motor has been turned off...seems also to be running hot). Any ideas? Been a long day trying to sort this out. Thanks!
