The ports labeled "IN" and "OUT" are on the transfer pump section of the IP.

Your no-start problem MAY be due, as the other posted stated, to a stuck metering valve, which is enclosed by the cover on the side of the pump where the valve mentioned in my picture is located. IF you decide to go that far into it, post back for some tips on getting the cover back on correctly.

Another cause could be a plugged return system. A Roosa pump will NOT inject fuel if the return is blocked, which can happen due to deterioration of the plastic governor damper ring.

Below is a link to a recent post showing photos of a failed governor ring and it"s replacement.Oh, yeah, the "spark plugs" you are seeing are actually glow plugs to pre-heat the air in the intake manifold for cold starting.

I took the entire cover with the three 5/16 screws off the side of the IP. Whoever designed that should be shot. Anyways I realized gas would pour out so I pinched the line. I've never worked on engines before but I take other things apart a lot so forgive my ignorance when it comes to tractors. Nothing seemed stuck although I messed with the levers up and down with the throttle and by hand for a bit. I put it back together and the engine started (yay!). I did not look for the "coffee grounds" you were mentioning. I did look at the post on it though and had read something similar before I asked this question.

So was this governor indeed stuck and I just didn't realize it? Do I still need to look for the coffee grounds or have I likely blown them clear and won't find them?

I believe I still have some sort of issue as the throttle has to be pushed forward with about 10-12 lbs of pressure to kill the engine. This is causing the bar shown in the picture to fall off. This is a fulcrum between the throttle bar? I doubt my terminology is correct but it is just put on with this little crappy metal clip and holds upside-down just waiting to fall off. Maybe this is to ensure you don't put too much pressure on the IP? Any ideas why this is happening? I checked that adjustment screw on the IP and it is not bottoming out before it gets hard to push.

Thank you for the help so far.

If your governor ring has disentegrated the engine will NOT maintain a steady RPM- it will constantly be speeding up and slowing down.
Something is out of adjustment if you have to apply pressure to the throttle to get it to shut off. The connecting bar should NOT pop off.
My 861D has been snorting white/gray smoke constantly for about 10 years or more but it still does what I ask of it so I don't worry.
Your oil leak is in the area that could be either the rear seal in the engine or a leaking transmission input shaft seal.

I won't try and bug you too much about these leaks and smoke.

I am more concerned with this bar popping off now. I don't think the governor ring is bad as the tractor RPM remains constant. Is there some sort of adjustment I can make to the throttle or do you think it is a mechanical issue with alignment? The throttle bars do not look bent or out shape by any means.
