jwatson, I opened the fuel pump, all seems fine, no splits etc... no spring in there tho, its the type that attaches to the carb.
A few more pictures and questions.
Peter C pointed out what looked like a piece of debris. As explained its the throttle plate (if thats what you call it) thats in the fully closed position. This seems strange as the other carb it closes fully. pics below.
Top carb in closed position - closes fully.
Bottom carb in fully closed position, theres a slight gap, should this be like this and if not in what position should it be, I noticed you turn the little screw on the side to adjust it.
I also pulled the plugs out, they are new but seems very dirty with particles on it, is that carbon? seems like some oil leaking from the top one. Also with them pulled out looking into the cylinder it appears theres a lot of the black build up inside the cylinder. Does anything here need attention and what does the plugs say in their state?
Where the plugs go in, cant see on the pic but seems very dirty inside looking in with a light.
