Ok I have been having problems with this engine since I got it. I have rebuilt the carb because it was in pieces when I received it. All parts are there for the carb. I am missing the spring that holds the timing base in the proper location. I am also missing the fuel pump, but that wouldn't keep it from running though. Cylinder compression is at 74 psi for number one and 75 for number two. I have a fat blue spark on both plugs even when barely pulling on the rope. The engine will only start if I spray fuel into the throat of the carb and it takes a few pulls to get anything. When it does start it only runs for about 2 to 3 seconds and the dies. It will do this for about 3 times before I have to prime it again with a spray bottle. I also have to start it with the choke closed. I have tried it with it open , but I have better results with it closed. I have removed and checked the reed valves and they seem new, only a very slight gap. I am not sure where the timing should be set or how to set it on this engine. The points I have set with the indicator dead on the top mark to right about .020 as indicated on the flywheel. The coils and all other ignition components look new and are functioning. I have pulled the head and the pistons are intact and the cylinders look pretty smooth with no evidence of scarring at all. I have checked everything I know to check to no avail. Any help would be greatly appreciated
