This is the first engine
I have ever rebuilt. It is a Kubota EA300 7hp single
cylinder and it runs my generator
. It is horizontal engine
got in the fuel
and ruined one of the valves. I had the valve reground and put it back together. I am trying to bench test it and it won't run.
I cannot find the correct adapter to do either a leak down or compression
test so I am trying to make one but am having problems with that.
I did take the injector off the block and run it against a piece of cardboard and it looks like it has a good spray pattern.
At first I was getting nothing out of the exhaust
but now I am getting what I believe is unburnt diesel
in a white cloud. NOrmally I would think water
but there is no heat in the exhaust
or the engine.
Could I have the timing set backwards so that fuel
is going in at the wrong stroke?
The injection pump is timed with shims so I don't think that that is wrong.
Also the engine is not giving any hint of wanting to start.
I am using a gravity to feed the injection pump but don't see that as a problem.
Any thoughts or ideas would be helpful.
I hope I don't have to take it apart again.
