Always glad to see you post another project Veggie.  Although I have no neighbors to worry about (thank God) I do get inquiries from shop customers that have noise concerns thus I follow engine muffling threads with interest. 

My own stand by set is powered by a 1115 china diesel and even thought it is 200 feet from the house my wife complained about the noise. At the suggestion of a sound engineer I did 3 things and the reduction was remarkable.
I turned the exit vertical, added 20 feet of pipe to the the exit "above ear level" and increased the pipe size to lower exit velocity.  The results were outstanding. I think they could be improved further with the use of a double wall chimney pipe. I have been watching the used market for the pipe.

Welcome
You are certainly not alone in setbacks with a Listeroid project. I have picked up a dozen or so over the years after people just gave up on them due to life's other needs. When you hear it run it will be very satisfying. There is a pretty good chance that the injector pintle will be stuck after sitting that long. If you have fuel delivery to the injector but not creak noise that's you clue to a stuck pintle.

Irregardless the of the suggested quantities the proper sump level is just below the bottom of the the fill hole when the upper sump is full. It hurts nothing to be higher but will cause seepage around the fill cap.

Hi, I also answered your question on the CS facebook page. I have sleeved quite a few since it is a more simple way to renew a CS bore without stocking dozens of various oversize pistons and ring sets.  If the installation instructions do not come with that sleeve don't use it. I use L.A. Sleeve and  Clevite. If your not doing the work yourself trust it to a shop that knows what they are doing as dry sleeve jobs can be(and are) screwed up by those who cannoy follow manufactures instructions.

Anyone who can laugh at that video is a big an idiot as the guys who did it,, in my (slightly) opinionated opinion.

Interesting how heating oil varies in different areas. Growing up on the farm the fuel truck filled up our heating oil tank and diesel tank in the same trip many times,, with the same fuel. Around these parts  the standard "fuel oil" is #2

It was unfortunate that all my pictures were lost when the photo host shut down this the reason for the vanishing posts here.  No pics equals rest of post worthless. That being said an enterprizing individual happened to save all of my rants so there is hope at some point they will be available with pictures.
Balancing and engine the best and easy way first requires you to get the counterweight in the correct position with respect to the keyway. This is something that is messed up often in India. It is very important step and something you cannot pass by if you want the engine to run as smooth as it can be. To do this requires that you get the engine exactly at top dead center. Then place vertical marks on the flywheels. After that you place the flywheels on a balancing stand as Bruce suggested your marks that you placed previously must be vertical when the flywheel is allowed to freely rotate with the heavy spot down. The Next step is to match the offset weight in the flywheels. The easiest way to do that is to add weight to the flywheel with the least amount of offset weight. To check offset weight requires that the lines you mark on a flywheel be held horizontal by temporary weights attached to the light side. once you have the weight in the correct position and respect to the key way and equally weighted both flywheels you reattach them to the engine and adjust the offset weight to smooth out the operation. If the engine has too much offset weight it will be a scooter while running it will tend to walk across the floor. If the engine has too little offset weight it will be a hopper, up and down. Realize that you are attempting to balance a up and down motion which is the weight of the piston and half of the connecting rod via a circular motion with offset weight in the flywheels. None of these engines well set perfectly still but they can be made very good if you take all the steps. My first attempt at balancing was via the chalk method and attaching weight and I was not successful at it either.

 The link provided here is of a metro 61 that I balanced with my method.
