I have a 6/1 driving a 5KW gen head and live in Falls Church, VA.  Any excuse to fire it up is appreciated!

email me and I'll be glad to have you over,

Easy way to tell if it is balance issue vs torque is to run it up to speed, note vibration and then shut off the fuel rack and open exhaust valve.

Immediately after fuel shutoff, during coast-down the nature of the vibration will change - motion at this point is balance related and not due to the powerstroke.

Try it - it's very noticable (for an engine not bolted to a ton of concrete).

Intuitively, the "chalk" method as described in "balancing out the bounce" thread seems easiest - and it appears that people who have done it have smooth running machines afterwards.

I could be blind, but I read:

"SUMMARY: This action promulgates national emission standards for
hazardous air pollutants (NESHAP) for stationary reciprocating internal
combustion engines (RICE) with a site-rating of more than 500 brake
horsepower (HP). "

Reading down further:

The final rule also does not apply to stationary RICE with a site-
rating of 500 brake HP or less. In reviewing the population database to identify
stationary RICE with a site-rating of 500 brake HP or less, we found
extremely little information. In discussions with State and local
permitting officials, the manufacturers, and some of the owners and
operators of stationary RICE, we found that such small stationary RICE
have generally not been regarded as significant sources of air
pollutant emissions. As a result, the small stationary RICE have not
been subjected to the same level of scrutiny, examination, or review as
larger stationary RICE. Little information has been gathered or
compiled by anyone for this subcategory of stationary RICE.
    Thus, at this point, we know very little about stationary RICE with
a site-rating of 500 brake HP or less. For example, we do not know how
many of the small stationary RICE exist. In addition, we know little
about the operating characteristics and emissions, the current use of,
as well as the applicability of, emission control technologies, the
costs of emission control for the small stationary RICE, or the
economic impacts and benefits associated with regulation. In the
absence of such information, we have concerns with the applicability of
HAP emission control technology to these stationary RICE. As a result,
we feel it is appropriate to defer a decision on regulation of
stationary RICE with a site-rating of 500 brake HP or less until
further information on the engines can be obtained and analyzed."

Maybe they are going to do more with these in the future, but this ruling does not affect my listeroid.

Why did I buy a listeroid?

The reason I told my wife?  It will make a reliable and quiet back-up power supply for our place at the coast that loses power on a regular basis.

The real reason?  It's cool and different with the flywheels and hand crank.  Plus I enjoy working on diesel engines (a CPA by trade, but really a frustrated engineer) - Rebuilt a 1959 Mercedes 190D with my grandfather the summer I was 16, and 20 some years later, I just got the oil out from under my fingernails from changing a timing belt on my VW diesel two weeks ago.  I could pay someone to ship me a diesel generator on a skid ready to go, but where is the fun in that?

This will be an opportunity to have another "toy" to play with that can be put to good use.
