I have a 1994 marathon that I just went over-new piston rings, valves, etc. Im getting plenty of spark and gas, but not even trying to start. engine is turning over fine
the compression is to low, HRC is right on with the valve adjustment. check to make sure you have 4 to 6 thousands Clearance, if thats all good then you need to check the cam timing and make sure the cam pulley is matched with the pin on the cam. if all that checks out? the problem is farther inside
