Default Re: Unleaded Gas

Speaking only for myself, I have never had any problem with these engines on unleaded fuel following a valve grind. As a qualification though, I have not needed to subject any of them to prolonged full-throttle operation.

The above applies only to the earlier engines that had a detachable intake manifold. I have indeed heard stories of problems with the later ones that had integral manifolds, but I have never owned one of those.
