PO said it has a mild cam........unknown further info on cam.

I can only start it using starter fluid, and have to keep spraying fliud in her til she gets a little warmed up. then runs on its own. Once warmed up she runs smooth, will idle with no issues.

It is pushing white smoke out of both exhausts (true dual exhaust)

I am buying a compression tester this weekend and will check the cylinder pressure.

Bad head gasket? Intake gasket? both?
