>>>*Go back and double check the timing chain. This is exactly what happens when the top gear is off one link.

When correct, the bottom timing mark will point straight down. The cam gear alignment dowel will point straight up. The actual top timing mark will be slightly left as you face it, at about 11:30 position.

The engine will run there, but poorly, and the distributor will be off enough it cannot be swung into proper time....*EB
