You're right, didn't notice the thickness of the rim in you avatar.  Point was, though, that the flywheels on Montana's engine aren't for an externally-balanced engine.  So some sort of balance weight should solve his problem.

Sad to read about someone so frustrated with balancing their engine they want to dump it.

FWIW, that flywheel with four holes spaced 90 degrees apart was intended for a crankshaft with internal balance weights. I suspect Mike's engine doesn't have internal balance weights, if his balance problem is so severe.

Again, sad to hear about someone so discouraged. It's not that difficult of a problem to fix with about 2 lbs of lead wheel weights on each flywheel rim.

Stan's engine in his avatar is a 10/1.  Two kidney-shaped cutouts at 90 and 270 degrees with a small round hole at 180 degrees and none at TDC.  The imbalance provided serves to counter the reciprocating forces.  Hmmm . . . if Stan could measure the diameter of the small hole, and the thickness of the web, and the radius of its center from the center of the crankshaft, we could calculate the weight of the missing balance weight.  Just thinking . . .

Tell me, Darren,

Did you get invited to many birthday parties when you were a kid? 

No?

I thought not.

Jack,

I don't think there is any easy to do this.  The wheels show evidence of having been balanced in India by the drill marks.  

On my 6/1  moving 7.5 oz of lead around on each flywheel rim had very little effect on the balance of my engine mounted on a 4x6" wood/steel trolley on casters.  I bet most of the motion that is blamed on balance issues is actually torque puses in the plane of the flywheels.

Hot water is one thing.  Steam is something else. 

It takes 1 calorie of heat to heat 1 gram of water one degree C.  Once you decide you're into making steam, that you will need 540 calories of heat to make 1 gram of steam.  Hot water makes more sense than steam unless you have a VERY LARGE source of energy, like a very large engine with oodles of waste heat.

Hmmm...so THAT'S what you meant when you were talking about _mounting_ your Listeroid in the shed!  You live too far from town!   ;)
I guess we all love our Listeroids in different ways.

Patents are one thing.  Trademarks are another. 
They're trying to protect their name; their reputation.
Imagine if someone found an Indian Lister clone and didn't understand the "clone" concept.
It might reflect badly on Lister's reputation.  I think that's what this is really about.

That's a good idea.  When working in familiar surroundings, we are constantly exposed to microbes and we develop immunity to most of them at a young age, so they cause us few problems.  However as T19 found out, when you are exposed to "bugs" from somewhere that your immune system may have never "seen" before (excuse the anthropomorphisms), your system can be in for quite a shock.  Traveler's diarrhea is one example that everyone is familiar with.  Get a scratch from a crate or piece of metal shipped from far away and you can end up like T19.  So it's probably a very good idea to be especially careful when opening crates containing green heavy metal from India (or Scotland).

Sorry.  It's been about a year since I last looked at mine.  Wasn't thinking.

John, it's no big nevermind.  Had the undersize gib key pop out on my 6/1, bounced off something and got batted by one of the spokes into my rippling rock-hard abs.  Left a nice scar.  Flywheel spun merrily along as if nothing had happened.  Killed the engine (thanking my Maker it didn't hit me in an eye) and the flywheel continued spinning on the crankshaft.  I think if Troy would just place some kind of collar on the crankshaft so the wheel can't come off and cause damage, running the engine shouldn't be a big thing.  However, I wouldn't go away and leave it running that way.  

Maybe a couple of hose clamps around the crank would be enough.  With the power and compression torque pulses twisting in opposite directions, it should pop loose, given some penetrating oil and time.  Maybe some ice in a suitable container with a little Jameson's poured over it might quell any misgivings you have about running the engine like that.

You know, I'm sitting here listening to the deafening silence, and I can't recalll if I've ever read that someone has replaced the crank bearings, which necessitates pressing off the timing drive gear.  Was it Hotater that was talking about that some time back?  Did a search and didn't find anything.

Just place some brass or steel shims between the rocker and the block and that will move the rocker arm over.

Hey, did you see the new 40 year old Barbie?

She comes with Ken's house, Ken's car, Ken's boat . . .

Best fifty kilobucks I ever spent!  [edit: ...and come to think of it, my X and I are now on better terms than we were for years prior. ]

Hotater,

As I recall you said some time ago that your particular engine was known to be bad and (I think you said) Joel initially didn't want to sell it to you and warned you off because he knew that there were problems with it, or that batch, or something.  But you wanted it, understanding that you would have to do major work to get it right.  That being the case, isn't your engine possibly a worst-case?  For the sake of context, can you refresh our recollection?
