Car has good compression good deal but will not start acts like the timing is off but it isn't I checked it upon trying to start it it backfires through the throttle body and then will almost stop cranking and then will start cranking again and backfire
Perhaps this can be caused by a Worn cam lobe. Remove both valve covers as U-turn and motor over watch the rocker arms they should all be pivoting the same. If you see one that is not pivoting properly that lobe on the cam is worn. Remove the rocker arm and push rod then we move the left. And inspect it for damage.
