Engines / Re: Rebuilding ST1

I've got all the parts from Gary Jones, and I need to hone the new cylinder that I purchased.  Any advice on technique, etc. I've been reviewing youtube videos, and have an idea as to what I should do, but am open to any recommendations

Thanks for the useful information.  I'm in the process of putting the engine back together and I don't see how I can press the bearing out of the main bearing housing?  Are there any special tools or techniques to get this done??

Have rec'd parts & beginning to put back together.   How do I change the main bearing?  I think I can make a tool to press the the one in the crankcase, but not sure hoe to deal with the other end.  Thanks for any advice.

Thanks for the comments.  I had some crocus cloth and I went ahead and lightly cleaned up the crank journal.  There was no roughness, but with a bit of careful effort, I was able to remove much of the discoloration from the bearing journal.  While at my local NAPA store, I rediscovered plastigage.  I checked the clearance and it's between .0055" and .006".  The maximum spec is .0055, but I think I'll go ahead with the rebuild (any concerns?).  Good comment re the oil pump.  I took it apart and found one of the o-rings was broken, but the clearances appeared good ok so I purchased the two required  o-rings along with a gasket kit for the engine.  I've also lapped in the valves as there was evidence of leakage.

As I've never been around one of these engines, and I'm replacing the piston and cylinder. I am looking for any break-in information as well as starting and operating information.  This unit has an electric starter so it should be easy to get it going.

Thanks for your comments
One last question, what is the oil reservoir and plunger that is screwed into the intake manifold?

I'm in the process of rebuilding an ST1 that ran for a short time with low oil.  The two main crankshaft bearings show signs of damage, but the crank journals look good with no damage.  The crankshaft rod journal bearing has more damage and the crank has some discoloration.  I can't feel any damage to the crank surface, but I'm wondering if I need to do something to clean the surface of crank journal?  With the tools I have I can't accurately measure the crank to determine if it is out of round.  Thoughts?

Also, I have a parts and shop manual for the engine.  Is there an operator's manual available for this engine?

Thanks in advance for comments and advice.

I'm working on an ST1 that needs new bearings oversize piston & rings, etc.  I need some help in finding a parts supplier.  Thanks for any assistance

I'm rebuilding a Lister ST1 and need general specs such as torques, clearances, etc.  I would also like to obtain a parts book
