I have 1957 mm445 industrial. The engine run fine with full power when I started to scoop some dirt with the bucket. The engine died when I tried to scoop compacted dirt, was push the engine and the hydraulic too hard I guess. Usually when this happen I was low on gas and I would pour a gallon and I would up and running with full power. But this time I cannot get the engine to it full capacity. The engine idles fine just a little weak. When I pull the throttle level to quickly the engine would choke and stop. I also saw some smoke shooting on top of the exhaust manifold when I first start. ( see blue circle)
I upload some pictures of what I think is the the intake manifold and the exhaust manifold. I can feel air coming out between the area where the intake manifold and the exhaust manifold is connected (red circle). Will the air leak cause the engine not achieve full power. I have to hold the choke lever half way for the engine to rev higher.
