I don't mean to go off topic in this thread... But I am gonna a little bit.  Sorry sir petteroid...

Cujet I have read quite a few of your posts over the last few years... I know you have been around here since the beginning.. My question is were you one of the original fella's to make the hollow oil dippers ? I know xyzer was one as well. Was wondering if you have them installed in your engines? 

Thanks.. and sorry again op..

Also maybe double check that the flywheel nut is properly tightened.. 

And also the nuts that hold the pulley on to the flywheel.
If either of these have loosened a bit, it will make some pretty loud knocking..

But as others have said these engines knock during startup to full speed..  Nature of the beast with these engines.

Cost you about $800-1000 to ship that $200 engine to the US.  I would grab that that engine if I were you and that is what you are looking for. I dont know where you are from but $500 is pretty reasonable asking price for a new s1115 engine.

They are diesels.. they do put out black smoke for a few seconds.. They most likely are adding some additives to the fuel.. Some top secret bio diesel??  I wound not think they are going to modify all those diesels to run on gasoline.

I have the ST1 complete service manual in pdf form. It describes what you are asking on pages 59-61..

It looks like forum will not let me upload the complete document.. But I can copy and paste the link .. try this..

''I had a stuck gib-key.  Nothing would move it.  So, I wound up machining a jig that fit perfectly into the key-way. Then, I spotted and drilled a "pilot hole" in the jig, that would keep the drill bit perfectly centered in the jig, ergo also the key.  A long drill bit of ~ 3/8 inch (I really don't remember) drilled it out.  I saved that jig in the Listeroid "fix-it" box, just in case I needed it again.''

That is a great tip.. In fact I was almost going to do something like that for one of the flywheels.

This one has some as well. Even a little is to much. But I am gonna flip this thing upside down. And get everything I can.

 I get what you were saying 38ac..  I should have just never posted the pic of that tool after 2 days of on and off beating on it.. It was a poor representation of what I was trying to show.. I kept adding different pieces of metal to the tool as I was going along instead of making something new each time. You guy's must have said what the hell is that thing lol.

But anyway I guess my biggest problem was I was using your advice 2 days before you posted it. About wacking the flywheel in while the puller was on it..  I was just not hitting it hard enough. Not nearly.. After I read your post I went out there and hit it like I meant it and how you said to do it, and whatta ya know it moved...

Guess I was worried to much about the India cast iron flywheel quality and thought I might break the dam thing..
Those flywheels are stronger than they get credit for..

So thank you 38ac.
